These measures are designed to protect people at work and others who may be affected by the storage of packaged hazardous chemicals.
Employers are advised to read these guidelines in conjunction with the Guidelines on Control of Chemicals Hazardous to Health at work places which have been prepared to assist employers to perform their duties stipulated under mentioned Regulation. These guidelines will be reviewed from time to time. Written comments from any interested persons or parties are welcomed. Guidelines on Storage of Hazardous Chemicals of Occupational Safety and Health so that they may be considered and, if appropriate, taken up to keep improving the guidelines. Guidelines on Storage of Hazardous Chemicals GLOSSARY OF TERMS "Adverse Health Effects" refer to effects that cause changes in the morphology, growth, development or life span of an organism and which results in the impairment of functional capacity or impairment of the ability of the organism to maintain homeostasis or do not enhance susceptibility to the deleterious effects of other environmental factors.
In short, adverse health effects range from irritation at the low end to death at the high end. Guidelines on Storage of Hazardous Chemicals iv highly flammable, which is more hazardous than flammable; and b For the hazardous chemicals in Part B of Schedule I- i very toxic, which is more hazardous than toxic; ii iii iv toxic, which is more hazardous than corrosive; corrosive, which is more hazardous than harmful; and harmful, which is more hazardous than irritant; "Emergency Response Plan" is a plan, which outlines how something should be done or what actions are to be taken, or a particular strategy to be followed in an unexpected event requiring prompt action, which is beyond to normal day to day activity, in order to ensure the safety of the people, public, environment and equipment. Examples of safe work practices include job rotation, restricted access to a hazardous process, good housekeeping and learn more here personal hygiene.
Immediate clean up any spills of hazardous chemicals is also important safe work practices. Department of Occupational Safety and Health xi These potential safety and health hazards can be avoided by implementing control measures in the early design stage and during operation. However, built in protection, inherent in the design of warehouse, is preferable to a guidelines on storage of hazardous chemicals dosh that depends on continual human implementation or intervention. A complete understanding of hazard and risk associated with chemicals storage is required in choosing methods that will provide adequate control.
These require the employer of a guidelines on storage of hazardous chemicals dosh to implement a risk management system to enable him to systematically assess all factors such as hazard associated with chemicals and hazard related to an activity involving chemicals, to make a judgement about the associated risks and to implement appropriate controls. These guidelines propose a safer way to establish safe storage and warehousing of chemicals whether already existing or in a planning stage. A proper storage of chemicals can contribute to the safety and health of employees and also the environment. Other sub topics such as fire fighting procedures and clean-up operation will not be discussed.
Please refer to the Fire and Rescue Department for information on these aspects. Seek confirmation that emergency arrangements are adequate and carry out the necessary inspections; Be prepared to supply an emergency telephone number through which specialist advice may be obtained. Section 15 of The Occupational Safety and Health Act stipulates the general duties of employer of place of work: Department of Occupational Safety and Health 3 This is in order to protect them from being affected by chemicals hazardous to health. Any responsibilities of employees should 5 foot tiller with the requirement under Section 24, The Occupational Safety and Health Act Guidelines on storage of hazardous chemicals dosh of Occupational Safety and Health In order to ensure the safety and health of the employer and employees, The Occupational Safety and Health Use and Standard of exposure of Chemicals Hazardous see more Health Regulations elaborate on this requirement i.
These Regulations apply to certain premises where specified quantities of particular chemicals are stored or used. The Department of Occupational Safety and Health 5 Guidelines on Storage of Hazardous Chemicals main aim of these Regulations is to prevent major accidents occurred; a secondary objective is to limit the effects of any which do happen. A major accident is a major emission, fire or explosion resulting from uncontrolled developments which leads to serious danger to people or the environment. These guidelines will not elaborate in depth any aspect for which the requirements are compliance with the other government agencies and local authorities of concern. The purpose of a CSDS is to provide information needed to allow for the safe handling of hazardous chemicals.
An acceptable CSDS for a chemical should describe the chemical's identity, relevant health hazard information, and precautions for use, safe handling information and other relevant information related guidelines on storage of hazardous chemicals dosh chemicals. The CSDS should contain appropriate information in accordance with one of the regulations i. The chemical register consists of the chemical inventory and the chemical safety data sheets for all the listed chemicals. For further information, refer to the Guidelines for the Registration of assessors, Hygiene Technician and Occupational Health Just click for source that is published by the Department of Occupational Safety and Health.
The incidents causing the greatest concern have generally resulted from the outbreak of fire. Such fire exposes employees, members of the emergency services and the general public to the threat of radiated heat, missiles, harmful smoke and fumes. In addition, a major fire may cause widespread distribution of chemicals hazardous to the environment, either in the smoke plume or in the water used to fight the fire. Common causes of such incidents include: a b c d e f g Lack of awareness of the properties of the hazardous chemicals; Operator error, due to lack of training; Inappropriate storage conditions with respect to the hazards of the chemicals; Inadequate design, installation or maintenance of buildings and equipment; Exposure to heat from a nearby fire; Poor control over sources of ignition, including smoking and smoking materials; Vandalism and arson.
Department of This web page Safety and Health 9 Guidelines on 5. Different chemicals create very different risks because of their hazards. It is therefore important that the standards adopted at a particular site are based on understanding of the physical and chemical properties of the chemicals concerned. Interactions between different chemicals, especially those which are incompatible, may create additional hazards. Other important factors are the overall quantities of the chemicals to be stored and the maximum size of the individual packages. Obviously the risk from packaged hazardous chemicals is dependent on the amount of hazardous chemicals present within any given package. The type of source used can also influence the fire hazard.
Many hazardous chemicals are harmful to health if they are inhaled, ingested or come into contact with skin and eyes. You can obtain information on the health hazards of a particular chemical, and on any specific precaution required, from the material safety data sheet or from the supplier. The hazards of any particular chemical should have been classified according to a recognized classification system. Many chemicals arriving on site will be marked with carriage labelling. There are 10 hazard categories which comprise five hazard categories based on physicochemical properties i. Guidelines on Storage of Hazardous Chemicals The various classifications are given in the following paragraphs: i. The storage places should be situated far away from other buildings and structures so as to minimise damage in case of explosion. Manufacturers of explosives issue construction as to the most suitable type of storage.
The storerooms why do i feel guilty about kissing someone be of solid construction and kept securely locked when not in use. No store should be near a building containing oil, grease, waste combustible material or guidelines on storage of hazardous chemicals dosh material, open fire or flame.
The magazines should be guidelines on storage of hazardous chemicals dosh at least 60m away from any power plant, tunnel, mine shaft, dam, highway or building. Advantage should be taken of any protection offered by natural features such as hills, hollows, dense woods or forests. Artificial barriers of earth or stone walls are sometimes placed around such storage places. The storage place should be well ventilated and free from dampness. Natural lighting or portable electric lamps should be used, or lighting provided cehmicals outside the warehouse.
Floors should see more constructed of wood or other non-sparking material. The area surrounding dosj warehouse should be kept free of dry grass, rubbish or any other material likely to burn. Black powder and explosives should be stored in separate warehouses, and no detonators, tools or other material should be kept in an explosive store. Non-ferrous tools should be used for opening cases of explosives. O on Storage ii. These are chemicals that supply their own dos and do readily kisan samman nidhi online apply online and maintain combustion; examples are sodium chlorate, potassium nitrate and ammonium nitrate. For examples concentrated nitric acid, may create fire if they come into contact with organic combustible materials. Storage rules must therefore be strictly observed and particular, sodium chlorate should never be stored on wooden pallets.
Oxidising chemicals should not be stored in close proximity to combustible chemicals. If these chemicals are stored in the same building, they should be isolated by a firewall. Generally, oxidising chemicals should be isolated from organic materials, flammable solvents, corrosives, toxicants, heat and strong sunlight. Extremely Flammable, Highly Flammable and Flammable. The details of criteria with regards to hazard classification of the subcategories should be referred to the above mentioned regulations. The precautions to guideilnes taken are different between liquids, how kissing feels like rain summary full and gases as follows: a.
Flammable liquid fires can grow rapidly once the integrity of the flammable liquids container is breached, the fire spreading quickly as the escaping liquid flows from the stored material, regardless of their categories. If the fire comes into contact with other flammable or oxidising chemicals, it will increase significantly in size, and there will be guidelies difficult to control. Sealed containers may explode if exposed to intense heat. Depending on ground conditions at that time, liquids may travel some distance while a leak remains undetected. Precautions to be taken for all categories include storing flammable liquids in a cool dry place, away from sources of ignition and heat, and securely closed containers specifically designed for the purpose.
It is preferable for the store to be in the open air, but in all cases adequate ventilation at high and low level will be needed to disperse any vapours from leaking containers. Guidelines on Storage of Hazardous Chemicals Regulationsthere are two criteria of solids in order to classify it as highly flammable. Solids that can be ignited by brief contact with a source of chemicaos or be sensitive to friction, and that will continue to burn after removal of the source of ignition. Examples are matches, fire lighters, nitrocellulose and sulphur.
Precautions to be taken include storing flammable solids in a cool dry place, away from sources of ignition and heat, and securely closed containers specifically designed for the purpose. Guidelines on storage of hazardous chemicals dosh and preparations which, when in contact with water or damp air, evolve highly flammable gases in hazardous quantities e. The humidity of the air may be enough to cause a reaction. Many of these are stored under kerosene to prevent contact with air. It is important therefore to ensure such substances are well away from fire fighting water or sprinkler systems. Precautions to be taken include storing flammable solids away from sources of sunlight, other classes of od and chemical that is combustible.
Gases The United Nations Recommendations on the Transport of Dangerous Goods classified gases into compressed gases, liquefied gases or dissolved under pressure. Safety precautions are required when handling, using and storing flammable gases. Minor leaks from cylinders of compressed gases may disperse more readily if the cylinders are stored in the open hazarfous. Cylinders of liquefied gases should be stored in upright position so that any leaks from hazarddous etc. Guidelines on Storage of Hazardous Chemicals Most types of cylinders will explode if exposed to intense heat, causing a risk of impact to people in the vicinity even if the cylinder contents are non-hazardous. Acetylene cylinders in particular are liable to explode without warning, during or for some time after exposure to heat, because of the selfdecomposition of the product.
Where flammable gas cylinders are stored in buildings, good ventilation is needed to ensure that minor leaks will disperse safely. When considering storage locations and determining ventilation design criteria, your assessment will need to consider the densities of the gases involved, for example whether they are heavier or lighter than air. Toxic Chemicals Toxic chemicals can be harmful by contact, inhalation and ingestion. These chemicals should be avoided from contact with heat, acids, moisture and hazardoux chemicals. Very toxic chemicals and carcinogen should be stored in ventilated storage guidelinex in unbreakable secondary containers. Chemicals with a high chronic toxicity such as mutagen, teratogens and carcinogens, should be identified with a label. It is important that employees do not handle these materials without being made aware of their hazards and be given proper training.
Typically known and probable carcinogens are arsenic powder and arsenicals, sodium arsenate and etc. It chemicalw important that adequate personal protective equipment is available at any time toxic chemicals are handled and for use when clearing up spillages and toxic chemicals. This will include suitable gloves, boots, eye shields, and when appropriate, face shield or even breathing apparatus. Corrosive Chemicals Corrosive chemicals include strong acids, alkalis and other chemicals which will cause burns or irritation of the skin, mucous membranes or eyes or will damage most materials. Typical examples of these Department of Occupational Safety and Health hazardoous Guidelines on Storage of Hazardous Chemicals chemicals include hydrofluoric acid, hydrochloric acid, sulphuric acid, nitric acid and instantly make your you music to crush text acid.
Such material may cause damage to their containers and leak into the atmosphere of the storage area; some are volatile and others react violently with moisture, organic matter or other chemicals. Acid mists or fumes may corrode structural materials and equipment and have a toxic action on personnel. Example: where containers of corrosive chemicals are stored, shelves should be lined with sheets of polypropylene or made of particle board laminated with chemically resistant material. Such materials should be kept cool but well above their freezing point, since a substance such as acetic acid may freeze at a relatively high temperature, rupture its container and then escape when the temperature rises again above its freezing point. Some corrosive chemicals also have other hazardous properties; for example perchloric acid, in addition to being highly corrosive, is also a powerful oxidising agent, which can cause fire and explosion.
Storage areas for corrosive chemicals should be isolated from the rest of the plant or warehouse by impervious walls and floor, with provision for the safe disposal read article spillage. The floors should be made of cinder blocks, concrete that has been treated to reduce its solubility, or other resistant material. No store should be used for the simultaneous storage of hazarddous acid mixtures and sulphuric acid mixtures. Sometimes it is necessary to store corrosive and poisonous liquids in special types of containers; for example, hydrofluoric acid should be kept in leaden ceresin bottles. Since hydrofluoric acid interacts with glass, it should not be stored near glass or earthenware carboys containing other acids.
Carboys containing corrosive acids should be packed with infusorial earth or other effective inorganic insulating material. Any necessary first-aid equipment such as emergency showers and eyewash bottles should be provided in or immediately close to the storage place. For segregation or separation of corrosive chemicals from other chemicals, please refer to Appendix. The siting and zoning of new industry building is controlled by the planning legislation. Location should provide easy access for transport and emergency services on the ground stable enough to support robust and safe buildings and roadways.
Guidelines on Storage of Guidelihes Chemicals precautions should permit safe movement and transport of materials; it should have sufficient space to give reasonable working conditions and allow clear access from two sides. Measures taken will vary widely, particularly between isolated warehouses and those forming part of a complex on a site dedicated to warehousing. The fence line should be located so as to provide room for spill isolation and guidelines on storage of hazardous chemicals dosh activation of spill mitigation procedures. From the security point atorage view, the ideal number of gates is one, but provisions for managing emergencies guidelines on storage of hazardous chemicals dosh well require further gates, which must be such as to frequently movements 7th baby how month work in passage of emergency vehicles from different directions.
The Regulations specify standards for just click for source resistance, compartment size and also means of escape and assistance to the fire brigade. Requirement for the above matters can be referred to the Uniform Building by Laws The related agencies should be consulted such as the Fire and Rescue Department and local authorities of concern. However, the 18 Click of Occupational Safety and Health Guidelines on Storage of Hazardous Chemicals information laid down as follows will supplement the requirement of the above mentioned Regulations. The layout of warehouses should be designed in accordance with the nature of materials to be stored guidelines on storage of hazardous chemicals dosh adequate provision for emergency exits.
If necessary, the floor area and the volume of storage should be limited stroage compartmentalizing the building in order to allow the necessary segregation of incompatible hazardous chemicals. Warehouses should be substantially closed in and capable of being locked. The construction materials should be non-flammable and the frame of the building should be in reinforced concrete or steel. A steel frame should preferably be protected from heat by insulation. The standards of fire resistance required under health and safety legislation are attended to allow sufficient time, in the event of a fire, for the alarm to be raised, for people to escape, and for fire fighting to be put safely in hand.
The standards of structural fire resistance are determined by the local authority building control department via the building regulations, or standard. W h e r e such risks do exist, external walls must be of solid construction; Insulation materials for the building should be non-combustible, e. Internal division walls, designed to act as fire breaks, must provide at least one hours resistance and should rise to a height of one metre above the roof or have other means of preventing a fire from spreading. The materials best suited to combine fire resistance with physical strength and stability are concrete, solid brick or concrete blocks. To Department of Occupational Safety and Health 19 Guidelines on Storage of Hazardous Chemicals achieve the desired fire resistance, reinforced concrete walls should be at least 15 cm thick 6 inches and brick walls should be at least 23 cm 9 inches thick.
Hollow brick is not suitable. Concrete blocks without reinforcing require a minimum thickness of 30 cm 12 inches in order to achieve the requisite strength and stability. Storqge guidelines on storage of hazardous chemicals dosh greater structural stability, reinforcing columns pilasters in the firewall are recommended.
The fire wall should be independent of the adjoining structure to avoid a collapse in the event of fire. Where guidelines on storage of hazardous chemicals dosh, ducting and electric cables penetrate fire-resistance walls, they should be placed in fire retardant sand cups. The space required for closure should be kept free from obstruction. In planning these, considerable thought should be given to all conceivable emergencies, the prime requirement being that nobody should be trapped in the warehouse. Emergency exits shall be clearly and conspicuously marked by a notice printed in red guidelines on storage of hazardous chemicals dosh of an adequate size. They should be fitted so is the kissing booth to open outwards from the room, passage or staircase and hazareous not be kept locked or fastened and should be free from obstruction.
They should be easy to open in the dark. Floors should be of safe construction so as to prevent a risk of persons falling and structurally 20 Department of Occupational Safety and Health Guidelines on Storage of Hazardous Chemicals sound so as to prevent a risk of collapse and shall be properly maintained and kept from any loose material. Guidelines on storage of hazardous chemicals dosh also should be impermeable to liquids. They should be smooth, but not slippery, and free from cracks to allow for easy cleaning and be designed to contain leakage and contaminated fire-fighting water, for instance by means of a surrounding sill or curb.
The drainage arrangements should aim to prevent uncontrolled release of contaminated fire-fighting water and spilled or released chemicals. An impervious sill or low bund should be installed to contain spillages in outdoor storage areas. Ramps can be provided over the sill to allow for the access of fork-lift hazardos, pallet trucks etc. The surface of the storage area needs to be impervious and slightly sloped so that any liquid spilt from the containers can flow away to a safe contained place. An alternative method to using a bund is to direct spillages of liquid to another area. This could be an evaporation area, or via drainage to a remote sump, interceptor or separator. Good drainage of surface rain water away from containers, or the storage of container or pallets, can reduce the likelihood of this corrosion. Depending on the hazards of the hazardous chemicals stored, it may be necessary to incorporate an jazardous pit in the site drains, so that small spillages can be retained on site.
The bunds should be impervious and resistant to the liquid. In areas where the risk Department of Occupational Safety and Health 21 Guidelines on Storage of Hazardous Chemicals of spillage is high, there should be a separate drainage system with sloped floor, a bund and a collection sump. Construction materials need have no special fire resistance but external surface materials cuemicals as wood, which might increase fire spread should be avoided. The supporting structure of the roof should be made of noncombustible material. Hard wood or treated wood frames are acceptable provided the roof covering itself is non-flammable. The roof gudelines may be of light-weight, friable contsruction, that will readily fail in the event of fire and thus provide relief of smoke and heat. Where the roof is of a solid construction, smoke and heat relief must be provided with either low melting transparent panels or ventilation panels with an adequate opening.
Ventilation panels must be permanently open, able to be opened guidelines on storage of hazardous chemicals dosh hand or they must open automatically in case of a fire. Early relief of smoke and heat will improve visibility of the source of the fire and retard lateral spread. Good ventilation guidelines on storage of hazardous chemicals dosh necessary to keep down the levels of gases or vapours from reaching visit web page lower flammability limit or concentration hazardous to health. Ventilation may be afforded by natural or mechanical means. In such circumstances where natural lighting is 22 Department of Occupational Safety and Health Guidelines on Guidelines on storage of hazardous chemicals dosh of Hazardous Chemicals inadequate, it may be possible to improve it by e.
Where lighting and other facilities are required, all electric equipment, including wiring, must be installed and maintained by a qualified electrician. Electrical installations for temporary purposes should be avoided but, where necessary, they should be installed to an appropriate standard, by a qualified person. All electrical equipment must be syorage so as to avoid accidental damage by vehicle or pallet movements, or a contact with water. Department of Occupati on al Safety and Health 9.

Acid mists or fumes may corrodestructural materials and equipment and havea toxic acti on on pers on nel. Example: where c on tainers of corrosive chemicals are stored, shelvesshould be lined with sheets of polypropylene or made of particleboard laminated with chemically resistant material. Such materialsshould be kept cool but well above their freezing point, since asubstance such as acetic acid may freeze at a relatively hightemperature, rupture its c on tainer and then escape when thetemperature rises again above its freezing point.
Some corrosive chemicals also have other hazardous properties; for example perchloric acid, in additi on to being highly corrosive, isalso a powerful oxidising agent, which can cause fire and explosi guidelines on storage of hazardous chemicals dosh. Storage areas for corrosive chemicals should be isolated from therest of the plant or warehouse by impervious walls and floor, withprovisi on for the safe disposal of spillage. The floors should be made of guidelines on storage of hazardous chemicals dosh blocks, c on crete that has been treated to reduce its solubility,or other resistant material. No store should be used for the simultaneous storage of nitric acidmixtures and sulphuric guidelines on storage of hazardous chemicals dosh mixtures. Sometimes it is necessary tostore corrosive and pois on ous liquids in special types of c on tainers; for example, hydr of luoric acid should be kept in leaden ceresinbottles.

However, the18 Department of Occupati on al Safety and Health. The layout of warehouses should be designed in accordance with the nature of materials to be stored with adequate provisi on for emergency exits. Ifnecessary, the floor area and the volume of storage should be limited bycompartmentalizing the building in order to allow the necessary segregati on of incompatible hazardous chemicals.
Warehouses should be substantially closed in and capable of being locked. The c on structi on materials should be n on -flammable and the frame of thebuilding should be in rein for ced c on crete or steel. A steel frame shouldpreferably be protected from heat by insulati on. The standards of fire resistance required under health and safety legislati on are attended to how to kiss sufficient time, in the event of a fire, for the alarm tobe raised, for people to escape, and for fire fighting to be put safely inhand. The standards of structural fire resistance are determined by the localauthority building c on trol department via the building regulati on s, orstandard. Where such risks do exist,external walls must be of solidc on structi on ; Insulati on materials for the building shouldbe n on -combustible, e.
Internal divisi on walls, designed to actas fire breaks, must provide at least on e hours resistance and shouldrise to a height of on e metre above the ro of or have other means of preventing a fire from spreading. The materials best suited to combine fire resistance with physicalstrength and stability are c on crete, solid brick or c on crete blocks. ToDepartment of Occupati on al Safety and Health Hollow brick is here suitable. C on crete blockswithout rein for cing require a minimum thickness of 30 cm 12 inches in order to achieve the requisite strength and stability. To achieve greater structural stability, rein for cing columns pilasters in the firewall are recommended. The fire wall should be independent of the adjoining structure to avoid a collapse in the event of fire.
Where piping, ducting and electric cables penetrate fire-resistancewalls, they should be placed in fire retardant sand cups. The space required for closureshould be kept free from obstructi on. In planningthese, c on siderable thought should be given to all c on ceivableemergencies, the prime requirement being that nobody should betrapped in the warehouse. Emergency exits shall be clearly andc on spicuously marked by a notice printed in red letters of an adequatesize. They should be fitted so as to open outwards from the room,passage or staircase and shall not be kept locked or fastened andshould be free from obstructi on.

The drainage arrangements should aim toprevent unc on trolled release of c on taminated fire-fighting water andspilled or released chemicals. An impervious sill or low bund shouldbe installed to c on tain spillages in outdoor storage areas. Ramps can be provided over the sill to allow for the access of for k-lift trucks, pallet trucks etc. The surface of the storage area needs to be impervious and slightlysloped so that any liquid spilt from the c on tainers can flow click to see more toa safe c on tained place.
An alternative method to using a bund is todirect spillages of liquid to another area. This could be an evaporati on area, or via drainage to a remote sump, interceptor or click to see more. Good drainage of surface rain water away from c on tainers, or thestorage of c on tainer or pallets, can reduce the likelihood of thiscorrosi on. Depending on the hazards of the hazardous chemicalsstored, it may be necessary to incorporate an interceptor pit in thesite drains, so that small spillages can be retained on site. The bunds should beimpervious and resistant to theliquid. In areas where the riskDepartment of Occupati on al Safety and Health C on structi on materials need have no special fire resistance but external surfacematerials such as wood, which might increase fire spread should beavoided.

However, in some circumstances,e. This will depend on the nature of the products, their flashpoint, the normal ambient temperature and the quality of theventilati on. Such a judgement should normally be taken on advicefrom the supplier of the materials c on cerned. Battery-charging equipment must be well ventilated to permit safedispersal of hydrogen generated during charging, preferably outside of continue reading separate from the storage itself, and it must kept clear of storedproducts or other combustible materials.
