Personal Protective Equipment
The minimal protective clothing and equipment when fumigating barrels or corks with sulfur dioxide gas includes a long-sleeved shirt and long pants, gloves, eye protection (full faceshield, goggles, or safety glasses with side shields and brow pieces), and chemical resistant gloves and boots. If the concentration of sulfur di- oxide in the work area, as measured by a atmosphere monitoring device (see “SO2 Monitoring” section below), does not exceed the amount specified on the pesticide label, respiratory protection is not required. However, keep the proper respiratory equipment available in case of an emergency.
Never wear contact lenses when working with SO2 gas. Contact lenses will absorb and trap vapors, plus their presence would complicate decontamination of the eyes in case of exposure. Vapors absorbed by a contact lens can cause serious eye irritation or injury.
Some situations require using additional PPE. For example, when using ap- plication equipment that is not equipped with wire-braided hoses, you must wear full-body protective clothing, gloves, and boots, all of which must be impervious to sulfur dioxide. In addition, you need to wear a face shield and approved respiratory protection.
Special respirators protect the lungs and respiratory tract from airborne SO2 gas. If the ambient air concentration of SO2 gas exceeds 2.0 ppm at any time, anyone working in or entering the fumigation area must wear a NIOSH/MSHA approved supplied air respirator or a self-contained supplied air respirator. Never use a cartridge respirator if you need to enter an area that has a high SO2 concentration. These are not approved for this type of use since they do not provide air for breathing and they have limited or no capacity to filter out the SO2 gas and adequately protect you.
Supplied Air Respirator. Supplied air respirators do not require filters or car- tridges to remove the gas because they provide an outside source of clean, uncon- taminated air. A length of hose connects the wearer to a distant air pump or large stationary air tank. This provides an unlimited quantity of fresh air. However, the range of available hose restricts the wearer’s mobility. The maximum hose length is
