Warehousing and storage: a guide to health and safety (HSG76): HSG76 / HSG 76 (Health and safety guidance, HSG76 / HSG 76)

Product Information

You must store wastes in sealed metal containers under cover if they have the potential for self-heating or self-reactivity. You must monitor the containers for heat build-up. Such wastes include rags and filter materials contaminated with metal swarf, low boiling point oils or low flash point solvents.

You must have measures in place to make sure that couplings are a correct fit. This will prevent couplings from loosening or becoming detached. You should provide, maintain and clean your own couplings and hoses to guarantee their integrity and fitness. You should also:You must direct overflow pipes to a contained drainage system (for example the relevant secondary containment) or to another vessel where suitable control measures are in place.

You must provide bunds for all tanks containing liquids (whether waste or otherwise) which could be harmful to the environment if spilled. Bunds must meet the CIRIA C535 or C736 standard and: HSG244: Remotely operated shutoff valves (ROSOVs) for emergency isolation of hazardous substances: Guidance on good practice make sure you take special care so that a coupling is able to withstand the maximum shut valve pressure of the transfer pump You must transfer wastes from containers into other storage vessels using a dip pipe, not by pouring. wastes containing Persistent Organic Pollutants ( POPs) with another material solely to generate a mixture below the defined low POPs contentYou must handle and store containers so that the label is easily visible and continues to be legible. All pipes, hoses, connections, couplings and transfer lines must be fit for purpose and resistant to the wastes being stored. You must use a suitable pipework coding system (for example, RAL European standard colour coding).

You must store aerosol canisters under cover in secure, well-ventilated containers, and within caged storage areas. You must also store them in a well-vented place that is not subject to extreme temperatures or direct sunlight. You must not store canisters in open containers to prevent the risk of them spreading fires by ‘missiling’ or ‘ejection’. This guidance is issued by the Health and Safety Executive. Following the guidance is not compulsory and you are free to take other action. But if you do follow the guidance you will normally be doing enough to comply with the law.”HSG251: Fumigation: Health and safety guidance for employers and technicians carrying out fumigation operations
