PHYSICAL DANGERS:


CHEMICAL DANGERS:
Reacts violently with with aluminium and magnesium powders, and with chlorinated rubber on heating causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as respirable fraction) 2 mg/m3 as TWA; (ACGIH 2004). TLV: (as respirable fraction) 10 mg/m3 as STEL; (ACGIH 2004).
MAK: (as fume) 1 mg/m3, Respirable fraction;
Peak limitation category: I(1);
(DFG 2003).
OSHA PEL†: TWA 5 mg/m3 (fume) TWA 15 mg/m3 (total dust) TWA 5 mg/m3 (resp dust)
NIOSH REL: Dust: TWA 5 mg/m3 C 15 mg/m3
Fume: TWA 5 mg/m3 ST 10 mg/m3
NIOSH IDLH: 500 mg/m3 See: 1314132


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly especially for zinc oxide fume particles.

EFFECTS OF SHORT-TERM EXPOSURE:
Inhalation of fumes may cause metal fume fever. The substance as a fume is irritating to the respiratory tract . The effects may be delayed. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
