4Regulatory Framework Canada Labour Code Part II Canada Occupational Health and Safety Regulations (COHSR) linkedwith disease prevention:– Workplace Hazardous Materials Information System (WHMIS)– Hazardous Substances Regulations– Levels of Sound Regulations– Lighting Regulations– Confined Spaces Regulations– Safety Materials, Equipment, Devices and Clothing– Hazard Prevention Program Regulations– Violence Prevention in the Work Place– Hazardous Occurrence Investigation, Recording and Reporting Standards referenced in Regulations
5Purpose of Canada Labour Code Part II“…prevent accidents and injuries to health…”“Preventive measures should consist first of the eliminationof hazards, then the reduction of hazards and finally, theprovision of PPE, … . All with the goal of ensuring the healthand safety of employees.”
6Hazard investigationThe COHSR require that if there is a likelihood that the health or safetyof an employee in a work place is or may be endangered by exposure toa hazardous substance, the COHSR require that the employer carry outan investigation.
7In the investigation the following criteria must be considered:• chemical, biological and physical properties of a hazardoussubstance• routes of exposure• acute and chronic effects• quantity of the substance handled• manner in which the substance is stored, used, handled anddisposed of• control methods• concentration or level of the substance
8Hazard investigation report must contain:• Observations respecting the criteria considered• Recommendations respecting the manner of compliance• Recommendations respecting sampling and testing methodsThe employer must develop and maintain a written procedure for thehazard control.A report must be kept by the employer for a period of 30 years.
9Occupational exposure limitsThe COHSR require that an employee be kept free from exposure to aconcentration of an airborne chemical agent in excess of the value forthat chemical agent adopted by the ACGIH, in its publication entitledTLVs and BEIs Based on the Documentation of the Threshold LimitValues for Chemical Substances and Physical Agents & BiologicalExposure Indices.Note: ACGIH TLV review process is being developed to allow for the new TLVs where the referencedTLVs are not suitable, to be reviewed by the stakeholders and the Labour Program (federal authorityhaving jurisdiction) and if a new occupational exposure limit is proposed, to recommend the change tothe Minister of Labour for adoption.
10Sampling and testing methodsIt is required that air samples of the chemical agent be takenand the concentration determined in accordance with: the standards set out by the US National Institute forOccupational Safety and Health (NIOSH) in the NIOSH Manual ofAnalytical Methods equivalent (or better) method to collect and analyze arepresentative sample other scientifically proven method
11Control of hazardsCOHSR require the employer to take preventive measures to protectemployees from exposure to a hazardous substance that is used,handled, processed or stored in the workplace.Control measures must be taken in the following order of priority: elimination of hazard reduction of hazard provision of personal protective equipment, clothing, device or material administrative procedures
12Medical examinationsWhere a hazard investigation report recommends a medicalexamination for the employee, the employer must: consult a physician not permit the employee to handle the substance unless a physiciandeclares the employee– fit, or– fit with specified restrictions to handle the hazardous substance
13Reporting occupational diseasesWhen an employer becomes aware of an occupational disease affectingany of his employees in the course of employment, the COHSR requirethat the employer take necessary measures to prevent a recurrence of the occupationaldisease submit to the Minister a written report indicating the number ofoccupational diseases during the 12 month period
14Hazardous occurrence incident reportThe written report contains among other information– a description of the disease sustained by the employee The description is used by the Labour Program to classify (or “code”) theoccupational disease by type. The classification (or coding) is done using the CSA Z795-03, Coding ofWork Injury or Disease Information Standard, and specifically the Natureof Injury or Disease. The information is entered into the Labour Program Database, HazardousOccurrences module, for subsequent retrieval and analysis.
