chemical substances used.
• To evaluate the degree of exposure of
employees to the chemicals hazardous to
health.
• To evaluate the adequacy of existing control
measures.
• To conclude on the significance of the health
risk posed by chemicals hazardous to health.
• To recommend further appropriate control
measures to prevent or reduce risk.

RECOMMENDATIONS
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.
