Appendix B Substance Technical Guidelines for Ethylene Oxide
(7) For purposes of compliance with the requirements of Articles 141 through 148 of the General Industry Safety Orders, EtO is classified as a flammable gas. For example, 7,500 ppm, approximately one-fourth of the lower flammable limit, would be considered to pose a potential fire and explosion hazard.
(2) The sampling and analysis under this section may be performed by collection of the EtO vapor on charcoal adsorption tubes or other composition adsorption tubes, with subsequent chemical analysis. Sampling and analysis may also be performed by instruments such as a real-time continuous monitoring systems, portable direct reading instruments, or passive dosimeters provided measurements taken using these methods accurately evaluate the concentration of EtO in employees' breathing zones.
Appendix D describes the validated method of sampling and analysis which has been tested by Federal OSHA for use with EtO. The employer has the obligation of selecting a monitoring method which meets the accuracy and precision requirements of the standard under his or her unique field conditions. The standard requires that the method of monitoring must be accurate, to a 95 percent confidence level, to plus or minus 25 percent for concentrations of EtO at 1 ppm and to plus or minus 35 percent for concentrations at 0.5 ppm.
Employees shall be provided with and be required to wear appropriate protective clothing wherever there is significant potential for skin contact with liquid EtO or EtO-containing solutions. Protective clothing shall include impermeable coveralls or similar full-body work clothing, gloves, and head coverings, as appropriate to protect areas of the body which may come in contact with liquid EtO or EtO-containing solutions.
Employers must ascertain that the protective garments are impermeable to EtO. Permeable clothing, including items made of rubber, and leather shoes should not be allowed to become contaminated with liquid EtO or EtO-containing solutions. If permeable clothing does become contaminated, it should be immediately removed while the employee is under an emergency deluge shower. If leather footwear or other leather garments become wet from EtO they should be discarded and not be worn again because leather absorbs EtO and holds it against the skin.
Any protective clothing that has been damaged or is otherwise found to be defective should be repaired or replaced. Clean protective clothing should be provided to the employee as necessary to assure employee protection. Whenever impermeable clothing becomes wet with liquid EtO or EtO-containing solutions, it should be washed down with water before being removed by the employee. Employees are also required to wear splash-proof safety goggles where there is any possibility of EtO contacting the eyes.
