Immediately dangerous to life or health

Exposure to tantalum metal dust may cause eye injury and mucous-membrane irritation. The threshold limit value (TLV) in air is 5 mg/m, LD q is <400 mg/kg and the Occupational Safety and Health Administration (OSHA) time weighted average (TWA) exposure limit is 5 mg/m (47). The immediate dangerous to life or health (IDLH) concentration is 2500 mg/m (48). Whereas some skin injuries from tantalum have been reported, systemic industrial poisoning is apparently unknown (47). 

The Immediately Danger to Life or Health (IDLH) level for CO2, set by the National Institute for Occupational Safety and Health (NIOSH) is 50,000 ppm. At that level, vomiting, dizziness, disorientation, and breathing difficulties occur ifler a 30-minute exposure at a 100,000 ppm, death can occur after a few minutes, even if the oxygen in the atmosphere would otherwise support life.

Immediately dangerous to life or health (IDLH) levels are the ceiling limit for respirators other than SCBAs. Any exposures approaching the IDLH level should be regarded with extreme caution and the use of SCBAs for respiratory protection should be considered. 

Lethal concentrations (LC50S) for inhalation of carbon monoxide blood agents have not been fully established. However, immediately dangerous to life or health levels (IDLHs) for inhalation of these agents are as low as 2 ppm. 

IDLH Immediately Dangerous to Life or Health levels indicate that exposure to the listed concentrations of airborne contaminants is likely to cause death, immediate or delayed permanent adverse health effects, or prevent escape from the contaminated environment in a short period of time, typically 30 min or less. These values constitute a hazardous materials emergency in the workplace and require the use of a supplier air respirator (e.g., SCBA). 

Immediately Dangerous To Life or Health (IDLH) This is a standard set by the National Institute of Occupational Safety and Health (NIOSH) which limits exposure to any toxic, corrosive, or asphyxiant substance that poses an immediate threat to life, or would cause irreversible or delayed adverse health effects, or world interfere with an individual s ability to escape from a dangerous atmosphere.
