Wash skin: If the chemical is in liquid form,the worker should immediately wash the skin when it becomes <br /> contaminated. <br /> Remove: If chemical is in liquid form,work clothing that becomes wet or significantly contaminated should be <br /> removed and replaced. <br /> Change: No recommendation is made specifying the need for the worker to change clothing after the work shift. <br /> Provide:Eyewash fountains should be provided(when chemical is in liquid form)in areas where there is any <br /> possibility that workers could be exposed to the substance;this is irrespective of the recommendation involving <br /> the wearing of eye protection.Facilities for quickly drenching the body should be provided(when chemical is <br /> in liquid form)within the immediate work area for emergency use where there is a possibility of exposure. <br /> [Note: It is intended that these facilities provide a sufficient quantity or flow of water to quickly remove the <br /> substance from any body areas likely to be exposed. The actual determination of what constitutes an adequate <br /> quick drench facility depends on the specific circumstances.In certain instances, a deluge shower should be <br /> readily available,whereas in others, the availability of water from a sink or hose could be considered adequate.] <br /> (NIOSH, 2003) <br /> DuPont Tychem@ Suit Fabrics <br /> Normalized Breakthrough Times(in Minutes) <br /> . <br /> ................ <br /> CAS ........... <br /> ....................................... <br /> I Chemical Number i State QC SL I TF TP IC3 JBR LV RC TIS <br /> ----------- <br /> .................. <br /> I Hydrofluoric acid <br /> 1 <br /> (48-51%) 7664-39-3 Liquid 1>480 1>480 1>480 1>4801180 1>480 >480 >480 >480 >480 <br /> ............. <br /> I Hydrofluoric acid <br /> (70%) 7664-39-3 Liquid imm 139 139 1 imm. >480 <br /> .................... ------- <br /> i Hydrofluoric acid <br /> (92% at 90'Q 17664-39-3 Liquid' 167* 167* 167* 67* 67* <br /> ----------- <br /> Hydrogen fluoride <br /> (gas) 17664-39-3 r Vapor imm. 35 1 imm. imm. 11 17011 135 1135 13 5 >480 >480 <br /> 1- _'Jllk I.............................. ....... ............. <br /> ..................... <br /> Hydrogen fluoride <br /> ' 1 <br /> (liquid,0° Q 17664-39-3 50 Liquid 1 1290 1 <br /> Hydrogen fluoride <br /> I (liquid, 15°Q 71664-39-3 Liquid <br /> >480 <br /> L..............................................- _1 i <br /> ............ <br /> I Hydrogen fluoride <br /> I(liquid, 18°Q 7664-39-3 '1 Liquid 143 il 43 1 1 1 1 <br /> ...........
