What effect does increased temperature have on materials in hazardous locations?

In hazardous environments, increased temperature can have significant impacts on materials, particularly in terms of their ignition risk. Higher temperatures can elevate the likelihood that a material may reach its ignition point when exposed to a source of flame or spark. This is especially critical in locations where flammable gases, vapors, or dust are present, as the increased thermal energy can accelerate chemical reactions and reduce the energy required for ignition.

Materials may also become more reactive at elevated temperatures, making them more susceptible to combustion or contributing to an environment where explosive situations could arise more easily. Therefore, understanding the relationship between temperature and ignition risk is vital for ensuring safety in hazardous locations.
