PEL means Permissible Exposure Limit, as defined by OSHA: “8-hour Time Weighted Average.” – An employee’s exposure to any substance, which shall not exceed the 8-hour Time Weighted Average given for that substance, during any 8-hour work shift of a 40-hour workweek.

IDLH means Immediately Dangerous to Life or Health: An atmospheric concentration of any toxic, corrosive or asphyxiate substance that poses an immediate threat to life or would cause irreversible or delayed adverse health effects or would interfere with an individual’s ability to escape from a dangerous atmosphere. IDLH values are based on effects that might occur as a consequence of a 30-minute exposure.

Specifications: The chemical sensor in the Diborane cassette shows an easy to see color change. Half of the sensor window will change color. 

• Diborane is a colorless gas with an offensive odor. It is toxic by inhalation. Diborane is decomposed by water giving off hydrogen, another flammable gas and boric acid a non-regulated material. Its vapors are heavier than air. Long term exposure to low concentrations or short term exposure to high concentrations can result in adverse health effects from inhalation. It is used in electronics. Rate of onset: Immediate Persistence: Minutes to hours Odor threshold: 2.5 ppm Source/use/other hazard: Intermediate chemical manufacturing; very flammable.
• Diborane is a colorless gas at room temperature with a repulsive, sweet odor. It mixes well with air and easily forms explosive mixtures. Diborane will ignite spontaneously in moist air at room temperature. Diborane is used in rocket propellants, as a reducing agent, as a rubber vulcanizer, as a catalyst for hydrocarbon polymerization, as a flame-speed accelerator, and as a doping agent. It is also used in electronics to impart electrical properties in pure crystals.

 The Chameleon is the only hands-free, power-free, chemical detector for gases and vapors in air, allowing First Responders, Firefighters, EMS, Police Officers and Military to detect the presence of hazardous chemicals. No liquid sample required. The Chameleon may even be immersed in salt water or fresh water without affecting its performance. Developed under funding by the United States Marine Corps, the Chameleon is ideal for users to screen unknown hazards in their environment
