Skin: No special equipment is required.
Respiratory: Respirators fitted with filters certified to standard 42CFR84 under series N95 should be worn when dust is
present. If the dust concentration is less than ten (10) time the Permissible Exposure Limit (PEL) use a quarter or half mask
respirator. If dust concentration is greater than ten (10) times and less than fifty (50) times the PEL, a full-face piece
respirator fitted with replaceable N95 filters is recommended. If dust concentration is greater than fifty (50) and less than
two-hundred (200) times the PEL use a power air-purify (positive pressure) respirator with replaceable N95 filter. If dust
concentration is greater than two-hundred (200) times the PEL use a type C, supplied air respirator (continuous flow,
positive pressure), with full face piece, hood or helmet.

SECTION 11 — TOXICOLOGICAL INFORMATION
Effects of Acute Exposure
Potential irritant for skin contact, eye contact or inhalation.
Effects of chronic exposure
Perlite is a naturally occurring volcanic glass consisting of fused sodium-potassium-aluminum silicate. Tests conducted on
Perlite have not identified crystalline silica as being present above the detection limit (0.05%). Although there are not
published reports of adverse health effects from exposure to perlite dust, dust levels should be maintained below the OSHA
Permissible Exposure Limit for perlite and respirators used when airborne dust is present.
Irritancy of Product
Potential irritant for skin contact, eye contact or inhalation.
Skin sensitization
Respiratory sensitization
Possible through skin contact.
