In environments where corrosive fumes are present, certain materials are more susceptible to damage over time due to oxidation or chemical reactions.

Plastic is an appropriate choice to avoid in corrosive environments, as it may degrade or become brittle when exposed to harsh chemicals or corrosive elements commonly found in such areas. Plastics can emit harmful fumes when damaged, and their structural integrity can be compromised, leading to failure in safety-critical applications, such as gas appliances.

Stainless steel, copper, and brass, although they each have their limitations, are generally more resistant to corrosion compared to most plastics when exposed to harsh conditions. Stainless steel, in particular, provides good resistance in many environments due to its alloying with chromium, which forms a protective layer against corrosion. Copper and brass can be resistant in many cases, especially if they are maintained well, though they may tarnish and require more upkeep than stainless steel. However, they still stand up better than plastic in corrosive settings.

Understanding the properties of these materials is crucial for ensuring safe and reliable operation of gas appliances in various environmental conditions.
