Copyright 2003 by T.R. Consulting, Inc.

USING THE NIOSH POCKET GUIDE TO CHEMICAL HAZARDS (PREFERRED SOURCE) OR AN MATERIAL SAFETY DATA SHEET (MSDS), CHOOSE A CHEMICAL WHICH WOULD BE ROUTINELY ENCOUNTERED AS A PART OF YOUR WORK. IF YOUR EXPOSURES VARY FOR EVERY SITE ENCOUNTERED, CHOOSE A CHEMICAL WHICH HAS BEEN ENCOUNTERED IN THE PAST 6 MONTHS. STUDY THE INFORMATION CONTAINED IN THE DOCUMENT, ANSWERING THE FOLLOWING QUESTIONS. AS THIS IS AN EXERCISE TO ASSESS YOUR ABILITY TO USE PUBLISHED INFORMATION TO MAKE DECISIONS WHICH AFFECT SAFETY ON A SITE, ABBREVIATIONS ARE NOT TO BE USED. FOR EXAMPLE, THE POCKET GUIDE LISTS AN APPROPRIATE RESPIRATOR FOR A PARTICULAR LEVEL OF EXPOSURE AS “CCRFOV”. THE PROPER ANSWER WOULD THEN BE FOUND BY GOING TO THE RESPIRATOR ABBREVIATIONS IN THE INDEX AND RECORDING THE ANSWER AS “FULL FACE CHEMICAL CARTRIDGE RESPIRATOR W/ ORGANIC VAPOR CARTRIDGE(S)”. SAVE THIS PAGE AS YOU WILL NEED TO PROVIDE THE ANSWERS ON THE SUBMITTAL FORM ALONG WITH YOUR TEST ANSWERS.
