Schedule 1: List of Permissible Exposure Limit
3. Making Assessment of Risk of Chemical to Health – CHRA
Part IV, Regulation 9
Written assessment shall be conducted:
before starting any work which may expose or likely to expose any employee to any chemical hazardous to health
within one year from the effective date of this regulation for the existing work/ process
PURPOSE OF CHRA
To enable decisions to be made on:
Suitable control measures;
Worker training needs;
Monitoring; and
Health surveillance needs;
that are required to protect the health of workers
who are exposed to chemicals hazardous to
health at the workplace
5/16/2018

CONCEPT OF ASSESSMENT
Assessing the risk of a group of workers (work
unit) with similar risks at the workplace should
include the following considerations:
Identity and form of chemical being
used/released at the workplace
Health hazards
Method and level of exposure
Existing control measures and their
effectiveness
CONTENT OF ASSESSMENT
Regulation 9(2): An assessment should take into
consideration:
1) Potential risks
2) Method and steps of chemical usage
3) Health hazard criteria
4) Level of exposure
5) Risk to health 6) Control measures
7) Control measures for accidental release
8) Necessity for worker exposure monitoring
9) Necessity for health surveillance
10) Necessity for worker training and retraining
1) POTENTIAL RISK
Situation where there is a possibility of a worker
falling ill or sustaining injury from the normal use,
handling, storing, transporting or disposal, or
accidental/abnormal release of the chemical
Example: chemical sprays, clouds of dust, bad
work practices, worker complaints of
symptoms/diseases
2) METHODS AND PROCEDURES FOR USE / HANDLING OF CHEMICALS
• Method of handling
•Manual or Automatic?
• Type of process
• Closed or Open?
• Work Procedures
• Standard Operating Procedure
• Safe Operating Procedure

3) HEALTH HAZARD CRITERIA • Physical form: solid (fine powder, granules,
pellet), liquid, gas
•Chemical used/produced?
•Toxicity data
• Effect on health: Acute vs Chronic
4) LEVEL OF EXPOSURE
•Route of Entry
• Inhalation, skin absorption or ingestion
•Quantitative Assessment: Evaluation of actual
personal workplace exposure to chemical using accredited
numerical and mathematical analysis
• Sampling of airborne contaminants
• Qualitative Assessment: Evaluation of potential
personal exposure to workplace chemicals based on
personal experience and professional judgment
• Job observation
• Measurement of frequency, duration and intensity of
exposure

•Existing control measures
•Adequacy of existing control measures
•Suitability
• Use and Effectiveness
• Maintenance
• Additional suggestions / recommendations
7) MEASURES FOR ACCIDENTAL EXPOSURE
• Probability of accidental exposure? •Spillage
• Leakage
• Accident
• Control measures
• Spill kit
• Safety shower and eye wash fountain
• Emergency Response Plan (ERP)
4. Action to Control Exposure Part V, Regulation 14
• Carry out action or control measure to eliminate or reduce the actual or potential exposure of an employee to chemical hazardous to health, within one month after receiving assessment report
– Control to below PEL
– Control to ALARP for those chemicals without PEL
– Hierarchy of control measures
– Use of approved PPE
– Engineering control equipment to be inspected, examined and tested regularly
– Local exhaust ventilation system to be designed and commissioned by Professional Engineer
5/16/2018

Control Hierarchy Regulation 15 (1)
• Elimination of CHH
• Substitution of less hazardous chemical or process
• Total enclosure of process& handling system
• Isolation of work
• Modification of process parameters
• Engineering control equipment
• Safe work system and practices
• Approved personal protective equipment
Personal Protective Equipment (PPE)
• Should be a last resort, but may be necessary if:
– engineering controls inadequate or being installed
– administrative controls don’t do the job
– emergency response or spill cleanup
– supplement other control techniques if can’t achieve required level
• Depends upon human behavior
– proper selection, fit and comfort issues
• Hazard is still present with PPE …
43
Legislative Requirement: USECHH 2000
• Regulation 16. Use of approved PPE – Approved PPE shall be used as an interim measure while other preferred
control measures are being designed or installed; or
– Where the measures taken do not adequately control employee’s exposure to CHH
• The employer shall establish and implement procedures on – Issuance
– Maintenance
– Inspection and
– Training in the use of the approved PPE
• The approved PPE shall – Be suitable to the type of work in which they are employed
– Fit the employees
– Not adversely affect the health or medical condition of the employees
– Be in sufficient supply and readily available to employees who require it.
