Ø Storage
· TRANSPORTATION OF DANGEROUS GOODS
The container of a hazardous substance must be designed, constructed and maintained in good condition to contain the substance securely. The container must be reasonably resistant to the substance and any other substance it contacts. Where an open container could pose a hazard, the container must be kept sealed or covered when not in use. (Occupational Health and Safety Regulation 296/97, 5.20 – 5.22)
The amount of a hazardous substance in a work area must not exceed the quantity reasonably needed for work in progress, normally in one wok shift. Bulk or reserve quantities must be stored in a designated area separate from the work area. (Occupational Health and Safety Regulation 296/97, 5.23)
Incompatible liquids must not be stored so that they can mix if the container leaks or breaks. (Occupational Health and Safety Regulation 296/97, 5.24)
A hazardous substance must be stored in a designated area, in a manner that ensures that it will not readily fall, become dislodged, suffer damage, or be exposed to conditions of extreme temperature. (Occupational Health and Safety Regulation 296/97, 5.25)
A hazardous substance storage area must be designed and constructed to provide for the safe containment of the contents, be clearly identified by signs or placards, allow the safe movement of workers and equipment, have adequate ventilation and lighting and be in a location not normally occupied by workers. (Occupational Health and Safety Regulation 296/97, 5.26)
An emergency eyewash is required where workers’ eyes or skin may be exposed to harmful or corrosive materials. Only potable water may be used in plumbed eyewashes. Portable eyewashes may use potable water or isotonic saline solution.
Emergency eyewashes must be located within 5 to 10 seconds walking distance or 6 to 30 metres depending on risk. Access to eyewashes must not be inhibited. Eyewashes must be identified with signs and instructions for use.
Plumbed eyewashes must be tested monthly and the line must be flushed. Portable eyewashes must be protected from contaminants and the liquid replaced as necessary to prevent the growth of bacteria.
Employees must be trained in the location and proper use of the emergency eyewash. (Occupational Health and Safety Regulation 296/97, 5.85 – 5.96)
Compressed gas cylinders, not including aerosol cans, must be protected from physical damage, sparks, flames and excessive heat. Compressed gas cylinders must be equipped with a pressure relief mechanism. Cylinders must be stored upright and be secured against falling. Once empty, cylinders must be identified and stored separately from other compressed gas cylinders. A compressed gas cylinder must be marked to indicate its rated pressure and the type of gas it contains. (Occupational Health and Safety Regulation 296/97, 5.36 – 5.47)
Ignition sources must be eliminated or controlled wherever flammable liquids are handled, stored or used. (Occupational Health and Safety Regulation 296/97, 5.27)
Metal containers must be bonded and grounded while dispensing flammable liquids. If the flammable liquid is being dispensed from a plastic container that is larger than 23 litres, the static at the surface of the flammable liquid must be controlled.
If flammable liquids are dispensed in a flammable liquid storage room, there must be mechanical ventilation in the room, exhaust from the room must be vented outside and make-up air supplied, and the doors to the room must be self-closing. (Occupational Health and Safety Regulation 296/97, 5.28 - 5.30)
Flammable liquids must not be used for manual cleaning unless no suitable non-flammable liquid is available. If flammable liquids are used for manual cleaning, written work procedures must be implemented, quantities of flammable liquid used must be minimized, workers must be trained in safe work practices, and those work practices must be submitted to the board. (Occupational Health and Safety Regulation 296/97, 5.32)
There is a limit to the quantity of flammable liquids that may be stored outside a flammable storage area. A maximum of 600 litres of flammable liquids with a flashpoint less than 200oF may be stored outside a flammable storage area, of which a maximum of 100 litres may have a flashpoint less than 100oF.
A maximum of 5000 litres of flammable liquid may be stored in storage tanks.
A maximum of 500 litres of flammable liquids, of which 250 litres may be class 1, may be stored in an approved flammables cabinet. A maximum of three cabinets may be located in each room. (Occupational Health and Safety Regulation 296/97, 5.33)
Carcinogens are designated as K1, K2 or K3 (confirmed, suspected, possible). Reproductive toxins are designated R1 or R2 (proven, possible). Sensitizers are designated as Z.
Carcinogens, reproductive toxins and sensitizers must be replaced when possible. If elimination is not possible, an exposure control plan must be implemented to reduce expose as low as possible. (Occupational Health and Safety Regulation 296/97, 5.57)
A policy and procedures must be developed according to risk. Procedures must include reassignment. Workers must be informed about reproductive toxins and ways to minimize exposure. (Occupational Health and Safety Regulation 296/97, 5.58)
TRANSPORTATION OF DANGEROUS GOODS (TDG)
Employees who ship and receive dangerous goods must have TDG training and must carry a valid TDG training certificate at all times. (Transportation of Dangerous Goods Regulation 6.5 – 6.8)
