FIRE AND EXPLOSION HAZARDS
In the event of a fire, firefighters should use normal procedures which
include wearing NIOSH/MSHA approved self-contained breathing
apparatus. Flame and chemical resistant clothing, hats, boots, and gloves
should also be worn. Do not use water to extinguish the gallium arsenide.
Use dry chemical extinguishing agents, dry sand, or dry ground dolomite.
Remove material from the fire area only
if without risk.
See Section 4 of the gallium arsenide MSDS for additional information.
REACTIVITY WARNING
Gallium arsenide is incompatible with steam, acids, acid fumes, and quartz.
When gallium arsenide decomposes and/or reacts with incompatible
substances, poisonous arsine gas and hazardous oxides of gallium and
arsenic are produced. Additionally, molten gallium arsenide attacks quartz.
See Section 6 of the gallium arsenide MSDS for additional information.
ENVIRONMENTAL INFORMATION
During wafer processing, the wastewater generated must be monitored--it
cannot be allowed to flow freely into an open drain. Consult local, state, or
federal EPA regulations for proper disposal. The wastewater may be
collected in compatible 55-gallon drums for waste disposal through a
licensed facility. If available, the wastewater may be piped to a wastewater
treatment plant on-site.
In the event of a spill or leak, the company’s Hazardous Materials
Response Team should be notified. While wearing full protective
equipment, the response team should cover the spill with dry sand,
vermiculite, or any other approved absorbent material. Mix well and
carefully transfer the contaminated absorbent material to an approved
container used only for gallium arsenide waste. Do not mix used absorbent
materials from different spills without consulting the safety officer,
hazardous materials officer, or other designated person in your company.
Local, state, or federal EPA regulations should be consulted for proper
disposal. Consult your supplier for additional methods.
See Section 7 of the gallium arsenide MSDS for additional information.
