Estimated Sulfur Mustard and Agent VX Surface Removal Contaminant Levels (SRCLs) for adult airport employees and personnel.a
| CWA | Airport Employee/Personnel SRCL8bc Protective estimate (mg/cm2 surface, CWA continuous exposure) | Airport Employee/Personnel SRCL12bd Protective estimate (mg/cm2 surface, continuous exposure) |
| Sulfur mustard (HD) | 8.65 × 10−3 | 5.77 × 10−3 |
| VX | 9.56 × 10−3 | 6.33 × 10−3 |
aChemical formulae: HD, C4H8Cl2S; VX, C11H26NO2PS.
bAirport employee estimate includes various airport employees and personnel (all of whom are restrained from entering the facility until after the agent source is removed or neutralized, any decontamination process is completed, and monitoring has characterized workspace atmospheres as suitable for reoccupancy). Airport employee and personnel SRCL estimates incorporate contaminant transfer from hard and soft surfaces to the eye, skin, and mouth (incidental ingestion) as well as potential particle inhalation due to resuspension.
cSRCL8 assumes average exposure time (shift) of 8 continuous h (incorporates inhalation toxicity value for exposure durations ≤8 h).
dSRCL12 assumes maximal exposure time (shift) of 12 continuous h (incorporates inhalation toxicity value for exposure durations >8 h but ≤24 h).
