Spacecraft Maximum Allowable Concentrations for Hydrogen Fluoride

Aerospace Medicine and Human Performance, 2022
BACKGROUND: Spacecraft maximum allowable concentrations (SMACs) provide guidance on allowable chemical exposures for nominal and emergency situations aboard spacecraft. SMACs are set to mitigate or preclude potential crew health effects and performance degradation. Hydrogen fluoride (HF) gas is highly irritating.

Spaceflight Maximum Allowable Concentrations for Ethyl Acetate

Aerospace Medicine and Human Performance, 2023
INTRODUCTION: Ethyl acetate is a simple organic compound that occurs naturally and is used industrially as a solvent. It has been detected in the ISS atmosphere and is known to off-gas from building materials. As NASA astronauts have been and will be exposed to ethyl acetate during space missions, Spaceflight Maximum Allowable Concentrations (SMACs ...

Maximum Allowable Concentrations of Mixtures

American Industrial Hygiene Association Journal, 1962
Abstract In evaluating exposure to mixtures of toxic substances, conclusions are usually based solely on the concentration of the most toxic or major component. This procedure is in general logical only when the different substances act independently.

Revisions to Spacecraft Maximum Allowable Concentrations for Acetaldehyde

Aerospace Medicine and Human Performance
INTRODUCTION: Spaceflight Maximum Allowable Concentrations (SMACs) were previously developed for acetaldehyde in 1994. Acetaldehyde is commonly detected at low levels on the International Space Station, and at higher concentrations it might be expected to cause respiratory and eye irritation.

Spacecraft Maximum Allowable Concentrations for Manganese Compounds in Mars Dust

Aerospace Medicine and Human Performance, 2019
INTRODUCTION: Exposure to excess manganese (Mn) can cause multiple toxicological outcomes in humans, most notably neurotoxicity. Ample epidemiological evidence suggests that chronic, low-level exposure causes subclinical cognitive effects. Because NASA astronauts will be exposed to Mars regolith, Spacecraft Maximum Allowable Concentrations (SMACs ...
