First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Remove to fresh air. If not breathing, give artificial respiration or give oxygen by trained personnel. Keep warm. Get immediate medical attention.

Skin contact

Immediately wash skin with plenty of water for at least 20 minutes, while removing contaminated clothing and shoes. Get medical attention especially, if irritation develops, persists, or symptoms of overexposure become apparent.

Eye contact

Immediately flush eyes with plenty of water for at least 20 minutes. Assure adequate flushing of the eyes by separating the eyelids with fingers. Get immediate medical attention if irritation persists, or symptoms of overexposure become apparent.

Ingestion

If swallowed, call a physician or poison control center immediately. Never give anything by mouth to an unconscious person. Do not induce vomiting unless instructed by medical personnel. Get medical attention.

Immediate Medical Attention

Get immediate medical attention if irritation persists, or symptoms of overexposure become apparent (for eyes/skin). Get immediate medical attention (for inhalation). Get medical attention (for ingestion).

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Use dry powder or carbon dioxide when fighting a fire involving this material.

Unsuitable media

Water extinguishers are not recommended.

Firefighter Protection

As in any fire, wear self-contained breathing apparatus pressure-demand, NIOSH (approved or equivalent) and full protective gear.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Clean up spills immediately, observing precautions in the Protective Equipment section.

Environmental

Do not allow material to enter drains or streams.

Cleanup methods

Clean up spills immediately, observing precautions in the Protective Equipment section. Absorb spill with dry inert material such as dry sand, earth, or vermiculite, then place in suitable container.

Materials: dry sand, earth, or vermiculite

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

This product should be handled only by, or under the close supervision of, those properly qualified in the handling and use of potentially hazardous chemicals, who should take into account the fire, health and chemical hazard data. Care should be taken to prevent any chemical from coming into contact with the skin or eyes and from contaminating personal clothing.

Storage

Store in a cold, below 5 degrees celcius, dry, well ventilated area away from sources of heat and incompatible substances. Keep container tightly closed and cold when not in use.

Hygiene

Wash thoroughly after handling. Avoid contact with eyes and skin. Avoid inhaling vapor or mist.

Fire prevention

away from sources of heat

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Use appropriate engineering control such as process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits. Where such systems are not effective wear suitable personal protective equipment, which performs satisfactorily and meets OSHA or other recognized standards. Consult with local procedures for selection, training, inspection and maintenance of the personal protective equipment.

Hands

Wear appropriate protective gloves. Consult glove manufacturers for glove permeability data.

Eyes

Wear appropriate protective glasses or splash goggles as described by 29 CFR 1910.133, OSHA eye and face protection regulation, or the European standard EN 166.

Respiratory

A NIOSH approved air-purifying respirator with an appropriate cartridge or canister may be permissible under certain circumstances where airborne concentrations are expected to exceed exposure limits. Protection provided by air purifying respirators is limited to airborne concentrations that are typically within 10 times the exposure limit. Use a positive pressure air supplied respirator if there is any potential for an uncontrolled release, exposure levels are not known, or any other circumstances where air-purifying respirators may not provide adequate protection. A respiratory protection program that meets OSHAs 29 CFR 1910.134 and ANSI Z88.2 requirements must be followed whenever workplace conditions warrant a respirators use.

Skin/Body

Wear suitable protective clothing to prevent contact with skin.
