What solution of HTH is used to clean the gas mask lens?

• A. 0.5% HTH
• B. 1%
• C. 2%
• D. 5%

Answer: (B)

Cleaning the gas mask lens relies on using a mild, chlorine-based cleaner that disinfects without harming the lens or its seals. The standard strength is one percent HTH. This level provides effective cleaning and disinfection while protecting the lens coatings and rubber components from damage or residue that could obscure vision. Stronger solutions can be harsh on coatings and seals, whereas weaker ones may not disinfect adequately. After cleaning, rinse with clean water and dry the lens to avoid streaks.
