2.1 Classification of the substance or mixture

OSHA Regulatory Status: This chemical is considered hazardous by the United States 2012 OSHA Hazard Communication Standard (29 CFR 1910.1200). Self-Heating Substances and Category 2 Mixtures Combustible dust

Signal word

WARNING

Hazard statements

Self-heating in large quantities; may catch fire May form combustible dust concentrations in air

Precautionary statements

Keep cool. Protect from sunlight

Prevention

Wear protective gloves/protective clothing/eye protection/face protection • Keep away from all ignition sources including heat, sparks and flame • Prevent dust accumulations to minimize explosion hazard

Storage

Maintain air gap between stacks/pallets • Store bulk masses greater than 10 kg/ 22 lbs at temperatures not exceeding 50 °C/ 122 °F • Store away from other materials

2.3 Other hazards

Activated carbon (especially when wet) can deplete oxygen from air in enclosed spaces, and dangerously low levels of oxygen may result. Prior to entering a confined space that contains or previously contained activated carbon, the space should be evaluated for oxygen and carbon monoxide concentrations, and any other hazards, by a qualified person. Workers should also take appropriate precautions when dealing with spent (used) activated carbons which may exhibit hazardous properties associated with the adsorbed materials. Avoid dust formation. Powdered material may form an explosible dust-air mixture. If transferring product under pressure, avoid generation of dust if an ignition source is present. Activated carbons have high surface area which may cause self-heating during oxidation. See Section 5. Do not generate dust because airborne respirable crystalline silica may be generated.

Principle Routes of Exposure

Inhalation, Eye contact, Skin Contact Eye Contact: May cause mechanical irritation. Avoid contact with eyes. Skin Contact: May cause mechanical irritation. Avoid contact with skin. Inhalation: Dust may be irritating to respiratory tract. Provide appropriate local exhaust ventilation at machinery and at places where dust can be generated. See also Section 8.
