Selection and Safety Note
The 350°F statement describes MSA radiant-heat testing; it is not a continuous-use temperature rating or a worker heat-exposure limit. This is Type I protection for top impacts, not Type II lateral-impact protection. Class G is not equivalent to Class E. Select head protection from the workplace hazard assessment, confirm the markings on the product received, inspect the shell and suspension before use, and follow current MSA instructions for assembly, care, and replacement.
