## PURPOSE OF SURVEY

- Learn work practices, controls in school autobody programs
- Stimulate awareness of hazards
- Catalyst for requesting DOS consultation

## GENERAL SURVEY BACKGROUND

- List of 41 schools from MA Dept. of Education
- 3 schools do not have autobody program
- 37/38 programs returned questionnaire

- NATEF-approved		86%
- Frame work			36%
- Vehicles/week		.4 - 10

## EQUIPMENT

- Spray painting booth/room	100%
- -- Down-draft ventilation		  81%
- -- make-up air				  89%
- -- explosion-proof exhaust fan	  97%
- Paint priming outside booth	   16%

## SANDING, GRINDING, WELDING

- Use sanders w/ vacuum		64%
- Welding – exhaust system		43%
- Sanding/grinding – tarps		39%

## PAINTS AND SURFACE PREPARATION

- Water-borne basecoasts		  8%
- Chromate paints				29%
- Lead paints					15%
- Methylene chloride			  6%

## WORK PRACTICES

- Right-to-Know
- MSDSs					100%
- Container labeling			100%
- Training (teacher) in past yr.	  69%
- Student training				100%

## WORK PRACTICES

- Respirators
- 	program 					100%
- 	air-supplied respirator (spray paint)	  78%

- NFPA Class I, Division 1 location, including explosion-proof/intrinsically safe electrical equipment

## RECOMMENDATIONS - EQUIPMENT

- Air velocity in a spray booth	     100 fpm
- Spray painting distance from
-     potential ignition source			20 ft.

## RECOMMENDATIONS – SANDING, GRINDING, WELDING
