Hazards identification of bitumen 50/70

Appearance and odor: black viscous liquid at high temperatures, solid at ambient temperatures.

Safety hazards:

Bitumen 50/70 is normally handled at temperatures up to 160 °c. The major hazard is heat burns on skin in direct contact with hot bitumen 50/70. If bitumen 50/70 is overheated, flammable decomposition products may be formed, resulting into fire and explosion. Boil over of tanks due to presence of water. In confined spaces, hydrogen sulfide may accumulate and reach hazardous levels. Pyrophoric deposits may develop in bitumen 50/70 tanks which may self-ignite.

Health hazards:

Routes of exposure: inhalation, ingestion, skin or eye contact.

Skin contact:

Severe thermal burns (up to third degree). Shock. Other than heat burns, the hazards associated with skin contact are negligible. W here long and physical contact with bitumen 50/70 occurs, expert medical advice should be sought to the need of periodic skin examination and in case of any skin abnormality.

Ingestion:

May cause gastric irritation

Eye contact:

May cause irritation

Inhalation:

Inhalation of vapors (generated at elevated temperatures) or oil mists can cause irritation to the nose and the throat as well as nausea. It is possible for hydrogen sulphide to accumulate to lethal concentrations above hot bitumen 50/70 in the vapor space of bulk storage tanks.

First aid measures inhalation of bitumen 50/70

In case of problems due to excess fumes exposure, move victim to fresh air and provide oxygen if breathing is difficult. Get medical attention. If the victim has difficulty breathing or tightness of the chest, is dizzy, vomiting or unresponsive, give 100% oxygen with rescue breathing or cpr as required and transport to the nearest medical facility.

Skin contact:

Burns from hot bitumen 50/70: remove heat by immediately treating/plunging the affected part with cold running water for 10 minutes. After cooling, no attempt should be made to remove the bitumen 50/70 adhering to the skin since the cold bitumen 50/70 forms a sterile protective layer on the burnt area. If

For any reason the bitumen 50/70 must be removed, this can be done using slightly warmed medicinal paraffin. Seek medical assistance or hospitalization in all cases of serious burns.

Eye contact:

Flood eyes with plenty of water for at least 15 minutes, blinking as often as possible. Remove deposits around the eye, eyelashes and eyebrows by wiping carefully with a soft cloth soaked

With medicinal paraffin oil. Do not force eyelids open. If irritation  persists, obtain medical attention.

Ingestion:

Do not induce vomiting, get medical advice.  Give milk or water to drink. If vomiting occurs spontaneously, keep head below hips to prevent aspiration of liquid into the lungs. Do not give anything by mouth to an unconscious person.

First aid facilities

Eye wash fountains and safety showers should be available for emergency use

Advise to doctor

When it is absolutely necessary to remove adhering bitumen 50/70 from the skin, liberal amounts of warm medicinal paraffin can be used. If solvent treatment is required, washing with soap and water and then the application of a proprietary re-fatting or skin cleansing cream should follow.

Exposure controls / personal protection against bitumen 50/70

Engineering controls

Bulk  storage  tank  ventilation is  required due  to  the  accumulation of  fumes  at  operating conditions. Tanks, equipment and pipelines containing hot bitumen 50/70 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 50/70.

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.
