Handling and Storage

Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe

all warnings and precautions listed for the product. Keep in a tightly closed container, stored in a cool, dry, ventilated

area. Protect against physical damage.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:

- OSHA Permissible Exposure Limit (PEL):

2.5 mg (F)/m3 (TWA)

- ACGIH Threshold Limit Value (TLV):

2.5 mg (F)/m3 (TWA) A4 - not classifiable as a human carcinogen.

Ventilation System:

A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne

Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the

contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document,

Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.

Personal Respirators (NIOSH Approved):

If the exposure limit is exceeded and engineering controls are not feasible, a full facepiece particulate respirator

(NIOSH type N100 filters) may be worn for up to 50 times the exposure limit or the maximum use concentration

specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. If oil particles

(e.g. lubricants, cutting fluids. glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or

instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator.

WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.

Skin Protection:

Wear protective gloves and clean body-covering clothing.

Eye Protection:

Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
