Immediately Dangerous to Life or Health Concentrations (IDLH)
CAS number: 107-02-8
NIOSH REL: 0.1 ppm (0.25 mg/m3) TWA, 0.3 ppm (0.8 mg/m3) STEL
Current OSHA PEL: 0.1 ppm (0.25 mg/m3) TWA
1989 OSHA PEL: 0.1 ppm (0.25 mg/m3) TWA, 0.3 ppm (0.8 mg/m3) STEL
1993-1994 ACGIH TLV: 0.1 ppm (0.23 mg/m3) TWA, 0.3 ppm (0.67 mg/m3) STEL
Description of substance: Colorless or yellow liquid with a piercing, disagreeable odor.
LEL: 2.8% (10% LEL, 2,800 ppm)
Original (SCP) IDLH: 5 ppm
Basis for original (SCP) IDLH: The chosen IDLH is based on the statement by ACGIH  that 5.5 ppm results in intense irritation and 10 ppm or more is lethal in a short time [Henderson and Haggard 1943]. According to MCA , the irritation properties of acrolein are clearly evident at 1 ppm. ACGIH  reported that 1 of 6 rats died after being exposed to 8 ppm for 4 hours and all died from exposure to 16 ppm [Smyth 1956].
Existing short-term exposure: 1989 American Industrial Hygiene Association guidelines
(AIHA) Emergency Response Planning Guidelines (ERPGs):
ERPG-1: 0.1 ppm (60-minute)
ERPG-2: 0.5 ppm (60-minute)
ERPG-3: 3 ppm (60-minute)
National Research Council [NRC 1984] Emergency Exposure Guidance Levels (EEGLs):
10-minute EEGL: 0.1 ppm
60-minute EEGL: 0.05 ppm (tentative)
24-hour EEGL: 0.01 ppm (tentative)
ACUTE TOXICITY DATA
Lethal concentration data:
|Mouse||Albin 1962||875||-----||1 min||280 ppm (0.32)||28 ppm|
|Mouse||Albin 1962||175||-----||10 min||121 ppm (0.69)||12 ppm|
|Dog||Albin 1962||150||-----||30 min||150 ppm (1.0)||15 ppm|
|Rat||Carpenter et al. 1949||8||-----||4 hr||16 ppm (2.0)||1.6 ppm|
|Rat||Catilina et al. 1966||375||-----||10 min||259 ppm (0.69)||26 ppm|
|Hamster||Kruysse 1971||25.4||-----||4 hr||51 ppm (2.0)||5.1 ppm|
|Cat||Skog 1950||-----||674||2 hr||1,078 ppm (1.6)||108 ppm|
|Rat||Skog 1950||131||-----||30 min||131 ppm (1.0)||13 ppm|
Other animal data: RD50 (mouse), 1.68 [Alarie 1981].
Human data: It has been reported that 5.5 ppm results in intense irritation and marked lacrimation, after 60 seconds [Henderson and Haggard 1943]. Exposures to 1.8 ppm result in slight eye irritation after 1 minute and profuse lacrimation after 4 minutes [NRC 1981]. In volunteers exposed for 5 minutes, concentrations of 2 to 2.3 ppm produced severe irritation [Darley et al. 1960]. A 10-minute exposure at 8 ppm and a 5-minute exposure at 1.2 ppm elicited extreme irritation described as "only just tolerable" [Sim and Pattle 1957].
Revised IDLH: 2 ppm
Basis for revised IDLH: The revised IDLH for acrolein is 2 ppm based on acute inhalation toxicity data in humans [Darley et al. 1960; Henderson and Haggard 1943; NRC 1981; Sim and Pattle 1957].
