Immediately Dangerous to Life or Health (IDLH) Value Profile, 1,3-Butadiene [CAS® No. 106-99-0]
DHHS (NIOSH) Publication Number 2017-107 [CAS® No. 106-99-0]
Basis for IDLH value: Despite the availability of toxicity data capable of being used to calculate health-based estimates for 1,3-butadiene (see Tables 4 and 5), the majority of these estimates are greater than 10% of the lower explosive limit (>10% LEL). NIOSH has adopted a threshold of 10% LEL as a default basis for the IDLH values based on explosivity concerns [NIOSH 2013]. Since safety considerations related to the potential hazard of explosion must be taken into account, the IDLH value is set at the 10% LEL for 1,3-butadiene of 2,000 ppm.
