Which safety requirements are mandatory when using methyl bromide?

• A. Detection equipment and respiratory protection equipment are mandatory.
• B. Only respiratory protection is required.
• C. No protective equipment is required.
• D. Detection equipment is not required.

Answer: (A)

Detection equipment and respiratory protection are mandatory when using methyl bromide. This fumigant is highly toxic and can rapidly accumulate in enclosed spaces, so the label requires monitoring ambient concentrations with appropriate detection gear and ensuring proper ventilation. At the same time, workers must use respirators to prevent inhalation exposure during handling, application, or entry into treated areas. Together, these measures address both the need to detect dangerous levels and the need to limit personal exposure; without detection, leaks or dangerous concentrations could go unnoticed, and without respiratory protection, inhalation hazards remain even if monitoring is in place.
