RECOMMENDATIONSRECOMMENDATIONS

1. Substitute existing chemicals with less hazardous type of chemicals if feasible.

2. Consider work area isolation practice if air monitoring indicates high concentration of hazardous chemicals but adequate control measures must be available.

- Work unit: Belt Line – Leader/Operator

2. Continue to have isolation practice but adequate control measures must be available.

- Work unit: HD Assembly – Leader/Operator

3. Install proper ventilation system if air monitoring indicates high concentration of hazardous chemicals (above PEL) at work place.

- Work unit: Belt Line – Leader/Operator

HD Assembly – Leader/Operator

4. Continue to ensure the employees are implementing the existing work procedures.

5. Employees should wear proper and correct type of DOSH approved personal protective equipment (PPE) during handling of chemicals as shown in below:

Work unit Existing PPE Recommended PPE

Belt Line – Leader/Operator

Safety glasses, face mask and latex gloves: all chemicals

- Respirator (organic vapor cartridge)

5. Employees should wear proper and correct type of DOSH approved personal protective equipment (PPE) during handling of chemicals as shown in below:

Work unit Existing PPE Recommended PPE

HD Assembly – Leader/Operator

Cotton gloves: all chemicals - Safety goggles

- Respirator (organic vapor cartridge)

- Chemical resistance gloves

6. Establish PPE replacement and maintenance practice and relevant record must be kept.

7. Engage registered hygiene technician to carry out monitoring of exposure of employees to chemicals. The parameter of chemical to be monitored is depending on type of chemical used as shown in the following table:

Work unit Parameter

Belt Line – Leader/Operator - Acetone (in Cellite RM45s-1, Cellite RS-28 and Cellite 1313)

(NIOSH Method 1300)

- Isopropyl alcohol (in Cellite RM45s-1 and Cellite RS-28)

(NIOSH Method 1400)

- Methyl ethyl ketone (in Cellite 1313)

(NIOSH Method 2500)

-n-hexane (in Cellite 1313)

(NIOSH Method 1500)

- toluene (in Cellite 1313)

-(NIOSH Method 1501)

Work unit Parameter

HD Assembly – Leader/Operator

- Ethanol and isopropyl alcohol (in Denatured Ethanol IMS and IPA)

(NIOSH Method 1400)

- Methanol (in Denatured Ethanol IMS)

(NIOSH Method 2000)

- Oil mist (in EBL Grease)

(NIOSH Method 5026)

8. Biological monitoring shall be carried out if recommended and advised by occupational health doctor especially for exposure to chemicals listed in Schedule II of USECHH Regulations 2000 as indicated in table:

Work unit Parameter

Belt Line – Leader/Operator - n-hexane and toluene (in Cellite 1313)

9. Engage and consult occupational health doctor for health surveillance programme especially for employees who are exposed to chemicals which are concluded as having significant risk.

10.Continue to have training programme that related to chemical handling, safety and health issue at least once every two years and record of training shall be kept.

11. Display necessary warning sign (PPE wearing sign and chemical hazardous sign). Install emergency shower and eye wash facilities at work place.
