V(b). CHEMICAL SAFETY -- PERSONAL PROTECTIVE EQUIPMENT

Transcription

1 Protective equipment must be worn to guard against injury from routine or accidental events. Each faculty or supervising staff member is responsible for choosing appropriate protective equipment for his or her staff and students. The following guidelines will assist in selecting personal protective equipment. In addition to protective equipment, there are requirements for footwear and clothing in Chapter V(a). A. EYE PROTECTION In instructional laboratories using hazardous chemicals, goggles must be worn at all times. Student employees must also wear goggles when using hazardous chemicals. For research laboratories, each department and program will develop an eye protection policy. Faculty are responsible for assessing the hazards associated with their research, determining the appropriate eye protection within the requirements of the department or program policy, and communicating those requirements to their research students. In the case of shared labs, the faculty members should discuss appropriate eye protection to protect against all laboratory hazards. Eye protection meeting ANSI Standard Z87.1, as summarized below, is the minimum level of eye protection required. Department policies for research laboratories are included in Appendix V(b)-A.

2 B. GLOVES Decisions regarding the need to wear gloves and, secondly, the appropriate gloves are dependent on the hazard of the chemical, potential for contamination during the experiment and dexterity requirements. These decisions are made by individual faculty and supervising staff members. Proper glove selection is a function of the specific chemical resistance of the material as measured by permeation rate and breakthrough time. Disposable latex gloves have limited resistance to many commonly used laboratory chemicals. They should not be used in operations where contamination is anticipated and must be removed immediately and the hands washed should they become contaminated. More resistant gloves include natural rubber, neoprene, nitrile, butyl, Viton, and polyvinyl chloride. Recommendation of the glove manufacturer and the Material Safety Data Sheet for the particular chemical should be used in choosing the appropriate gloves. Information can be found at the following web sites. Ansell Chemical Resistance Guide at Best Manufacturing Company at C. CLOTHING Oklahoma State University at Washington State University at The purpose of protective clothing is to prevent contamination of the skin and to prevent the carrying of contaminants outside the laboratory. Street clothes may afford limited skin protection but may result in contaminants being carried outside the laboratory. Lab coats, or other protective clothing, must be worn when handling large quantities (greater than one liter) of Select Carcinogens (see Chapter V(i)), Reproductive Toxins (see Chapter V(j)), and Acute Toxins (see Section V(h)) which are readily absorbed through the skin as listed below; and when handling greater than one liter of concentrated (as supplied by the manufacturer) acids and bases. 1 Specialized protective clothing may be necessary in certain high hazard operations (e.g., hydrofluoric acid). 1 Lab coat requirements do not apply to the use of stationary containers equipped with pumps when less than one liter is being dispensed.

6 APPENDIX V(b) - A DEPARTMENT POLICIES FOR EYE PROTECTION IN RESEARCH LABORATORIES

7 EYE PROTECTION FOR RESEARCH STUDENTS IN THE CHEMISTRY DEPARTMENT It is the policy of the Chemistry Department that some form of eye protection must be worn whenever a student is working in a research laboratory. Safety goggles must be worn whenever particularly hazardous operations are being carried out, when a splash hazard exists, or when glassware under pressure or vacuum is being used. Approved safety glasses with side shields or prescription eye glasses (meeting ANSI Standard Z87.1) with side shields may be worn whenever operations of low hazard are being performed. In the case of uncertainty, students should assume that goggles are necessary. In instrument rooms, no eye protection is necessary when an individual is operating an instrument unless a particular hazard is associated with the use of that instrument. For example, in using lasers appropriate eye protection must be worn. However, when samples are being handled and prepared, particularly if a splash hazard exists, eye protection must be worn in accordance with the above guidelines. 12/8/95

8 EYE PROTECTION FOR RESEARCH STUDENTS IN THE BIOLOGY DEPARTMENT AND THE BIOCHEMISTRY PROGRAM It is the policy of the Department of Biological Sciences and the Biochemistry Program that all students working in laboratories wear eye protection for procedures carrying potential hazards such as those from: splashes or mists from hazardous chemicals, heat (sparks, hot vapors, or boiling fluids), flying objects, glassware under vacuum or pressure, UV radiation, or airborne particles (e.g., hazardous chemical dust). Faculty or staff members in charge of individual students or classes will be responsible for (1) identifying potential hazards, and (2) informing students of the type of eye protection required. All laboratory work must be assessed as to potential dangers from these hazards and eyewear required must meet the ANSI Standard Z87.1 (see list below). When there is a doubt as to whether or what type of eye protection is required, the chemical hygiene officer should be consulted. SUMMARY OF ANSI Z Approved Protective Eyewear 1.

9 EYE PROTECTION FOR RESEARCH STUDENTS IN THE NEUROSCIENCE AND BEHAVIOR PROGRAM (REESE ) Under the Direction of Will J. Millard Faculty, students, and staff are to wear safety splash goggles when hazardous operations are carried out. These operations include, but are not restricted to, the following: activities that result in a splash hazard handling of hazardous chemicals use of glassware under reduced or elevated pressure the use of explosive compounds the use of glassware in high-temperature operations Ordinary prescription glasses and contact lenses do not offer adequate protection and may not be substituted for safety splash goggles. 28 December 1995

10 EYE PROTECTION FOR RESEARCH STUDENTS IN THE GEOLOGY DEPARTMENT Clapp 17 - The Rock Room Safety glasses with side shields are required for the following operations: Clapp 9D use of the trim saw use of the thin section saw and grinder use of the crusher (ear protection is also necessary) use of the hydraulic rock splitter use of a sledge hammer to crack rocks Splash goggles are required for the following operations: Clapp 329 change acid on samples any other use of chemicals All acids represent a potential splash hazard and goggles MUST be worn at all times when acids are being handled. Splash goggles and a full faceshield (in addition to other protective equipment specified in "Clapp 329 Required Safety Precautions") must be used when using hydrofluoric acid. 5/08
