SWEEP UP AND CONTAINERIZE FOR RECLAMATION OR DISPOSAL. VACUUMING OR WET
SWEEPING MAY BE USED TO AVOID DUST DISPERSAL.
| 7. HANDLING AND STORAGE | |
KEEP IN A TIGHTLY CLOSED CONTAINER, STORED IN A COOL, DRY, VENTILATED AREA.
PROTECT AGAINST PHYSICAL DAMAGE. ISOLATE FROM INCOMPATIBLE SUBSTANCES.
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.
| 8. EXPOSURE CONTROLS/PERSONAL PROTECTION | |
AIRBORNE EXPOSURE LIMITS: NONE ESTABLISHED.
VENTILATION SYSTEM:
IN GENERAL, DILUTION VENTILATION IS A SATISFACTORY HEALTH HAZARD CONTROL
FOR THIS SUBSTANCE. HOWEVER, IF CONDITIONS OF USE CREATE DISCOMFORT TO THE
WORKER, A LOCAL EXHAUST SYSTEM SHOULD BE CONSIDERED.
PERSONAL RESPIRATORS (NIOSH APPROVED):
FOR CONDITIONS OF USE WHERE EXPOSURE TO DUST OR MIST IS APPARENT AND
ENGINEERING CONTROLS ARE NOT FEASIBLE, A PARTICULATE RESPIRATOR
(NIOSH TYPE N95 OR BETTER FILTERS) MAY BE WORN. 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-FACE 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.
