CHRA Objectives� To identify the potential hazards posed by each chemical substance used in production floor

� To evaluate the degree of hazardous chemical exposure

� To evaluate the adequacy of existing control measures

� To conclude on the significance of the health risk posed by the hazardous chemicals

� To recommend further appropriate control measures to prevent or reduce risks

Post CHRAPost CHRA

CHRA Methodology

� Each similar process with same chemicals used and same handling are grouped together under one work unit

� Conclusions derived from work practice observation, interviews and degree of hazards

� 5 conclusions derived

� C1 - Risk is not significant

� C2 - Risk is significant but adequate controls implemented

� C3 - Risk is significant but there controls currently implemented isnot adequate

� C4 - Uncertain of Risk: Insufficient information

� C5 - Uncertain of Risk: Uncertain about degree and extent of exposure


Post CHRAPost CHRA

Summary of Conclusion

� Total of XX Work Units assessed based on similar workgroup and chemicals used

� Conclusion

## work units have significant risk with adequate control but could increase in future (C2)

## work units has risk significant and no adequate control measures present (C3)

## work units has insignificant risk to health

Summary of C2 Findings

Involved 10 processes

Process Name Work LocationControl Measures

Present

Significant of Risk due

to…

Rubber Gloves, Air Purifying

Respirator: 3M 7200S/7286

Corrosive chemicals – used in

manner that can generate

airborne particulate

Welding face shield, Apron,

Leather Gloves

Toxicity of chemical – welding

produce several types of metal

fumes – manganese, iron

oxide, fluoride (from filler)

Rubber Gloves Toxicity of chemical used –

corrosives

Rubber Gloves, Apron Mikro Klene – Harmful by

Post CHRAPost CHRA

Summary of C3 Findings

Work Unit 1Insufficient ventilation in the current work area – contains many organic solvents

Varnishing, painting done in poorly ventilated area – basement car park

Work Unit 2Risk of direct skin contact with chemical: no hand protection used

Chemical – Acetone may be absorbed into the body via skin


Post CHRAPost CHRA

Actions To Be Taken

Assessment of Risk to Health (CHRA)

To be reviewed if there is significant changes to work unit

Significant changes include change of chemicals in the process or process change

Or, every 5 years and report kept for 30 years

19


Post CHRAPost CHRA

Actions To Be Taken

�Action to Control Exposure� Establish a Personal Protective Equipment (PPE) Program.

� Includes procedures for issuance, maintenance, inspection and training in the used of the PPE.

� Review ventilation design at the Work Area 1

� Inspect and test the LEV for Process 2 at work area 1


Post CHRAPost CHRA

Actions To Be Taken

Labelling and Relabelling

Relabel chemicals used in secondary container or chemical tank (Work Area 3)

Ensure that chemicals purchased are labelled according to CPL regulation
