Dimethylethylamine - DMEA - C4H11N
Main information on dimethylethylamine or “ DMEA ” (C4H11N), its physical characteristics, its effects on health, the means of detecting it (DMEA gas detector) as well as the appropriate respiratory protection equipment (gas mask or assisted ventilation device with anti-gas filter type ABEK ).
Main characteristics of dimethylethylamine - DMEA (C4H11N)
Dimethylethylamine (C4H11N) mainly known by the abbreviation " DMEA " is a gas very present in foundries. It is used as a crosslinking agent for synthetic resins (phenolic resins, polyurethanes), mainly used in the cold box core forming process in foundries. It is also a polymerization catalyst for polyamides.
Health Effects of Dimethylethylamine
Dimethylethylamine (DMEA) is a highly flammable gas, with explosive limits between 2.3% and 12% by volume. During combustion it releases highly toxic fumes containing ammonia, nitrogen and carbon oxides and traces of cyanide. It is also a toxic gas, harmful by inhalation (H332) and if swallowed (H302). It is highly irritating, and can cause skin burns and serious eye damage.
DMEA (dimethylethylamine) gas detection
Although detectable by smell, only a DMEA gas detector can accurately measure the concentrations of this gas. Two methodologies for detecting dimethylethylamine : either in toxicity with a measurement in ppm (recommended given its toxicity), or in explosiveness with a measurement in percentage of LEL (explosive gas detector).
Dimethylethylamine (DMEA) Respiratory Protection
Dimethylethylamine (DMEA) is an eye irritant, so a full-face mask is recommended for short-term interventions or a more comfortable assisted ventilation device with ABEK-type gas filters. If concentrations exceed 60 times the OEL, a self-contained breathing apparatus will be essential.
