Engineering controls
Bulk storage tank ventilation is required due to the accumulation of fumes at operating conditions. Tanks, equipment and pipelines containing hot bitumen 115/15 or heating medium, such as hot oil, should be adequately insulated to prevent accidental contact by personnel. Any surface that will reach a temperature of 70 oc must be insulated for personal protection. For personnel into confined spaces (e.g. bulk storage tanks), a proper confined space entry procedure must
Be followed, including ventilation and testing of tank atmosphere. Install eye washes and showers for emergency use.
Water should not be allowed into contact with hot bitumen 115/15.
Protective clothing :
Avoid contact with the skin and the eyes, and avoid breathing vapors or mists. Use chemical resistant gloves/gauntlets, boots, and apron. For spillage clean up use chemical resistant knee length boots. Where risk of splashing or in spillage clean up, use chemical resistant one-piece overall buttoned at neck and wrist, with an integral hood, of pvc.
Respiratory protection
If engineering controls do not maintain airborne concentrations to a level adequate to protect the worker’s health, an approved cartridge respirator with a replaceable organic vapor filter must be worn. Types to be considered include supplied air respirator, air purifying respirator for organic vapors, and self-contained breathing apparatus for use in environments with unknown concentrations or emergency situations.
Hand protection
Materials should provide suitable chemical protection: impervious pvc, neoprene or nitrile rubber. Suitability and durability of a glove is dependent on usage, e.g. frequency and duration of contact, chemical resistance of glove material, glove thickness, and dexterity. Always seek
Advice from glove suppliers. Contaminated gloves should be replaced.
Eye protection
Safety glasses with side shields or chemical splash goggles and/or full face shield to protect eyes and face if contact is likely. Provide an eye station in the area.
Skin protection
Chemically resistant impervious gloves, boots, suits and other items should preferably be pvc, neoprene or nitrile rubber to be used. Safety showers should be available for use.
Work/hygiene practices
If contamination occurs, change clothing and discard internally contaminated gloves and footwear. Launder contaminated clothing before reuse. Ensure a high level of personal hygiene is maintained. Always wash hands before eating, drinking, smoking or using the toilet.
