SECTION 3: PHYSICAL DATA
This item is a glass light bulb; chemical characteristics are not applicable.
SECTION 4: FIRE AND EXPLOSION DATA
Fire and explosion data not applicable. Under extreme heat outer glass envelope might melt or crack.
Inner arc tube is composed of polycrystalline alumina and is refractory material.
SECTION 5: REACTIVITY DATA
Stability: Lamp is stable.
Incompatibility: Glass envelope will react with hydrofluoric acid.
Polymerization: Not applicable
SECTION 6: HEALTH HAZARD DATA
Not applicable to intact lamp. The inner envelope is composed of polycrystaline alumina. Breakage of this
envelope may result in some exposure to elemental sodium and mercury. No adverse effects are expected
from occasional exposure to broken lamps. As a matter of good practice, breakage should be avoided.
Prolonged or frequent exposure to broken envelopes should be avoided through use of adequate ventilation
during disposal of large quantities of lamps.
EMERGENCY AND FIRST AID PROCEDURE: Normal first aid procedure for glass cuts if such occur
through lamp breakage.
SECTION 7: PRECAUTIONS FOR SAFE HANDLING AND USE
Normal precautions should be taken for collection of broken glass.
Waste Disposal Method: At the end of rated life, when this lamp is removed from service, it will be
subjected to the current Toxic Characteristic Leaching Procedure (TCLP) prescribed by the Environmental
Protection Agency. This test is used to determining whether an item is a hazardous waste or a non-
hazardous waste under current E. P. A. definition. These lamps would fail the TCLP test and would be
considered hazardous under the Universal Waste Rules. Generators should evaluate all of the disposal
options, which may be available in the particular state in which the generator’s facility is located. The
generator should check with federal, state and local officials for their guidance. Philips encourages recycling
