The Ingredient Disclosure List is not a list of
โ Job. Answer: A segment of work, a specific work assignment or a set of actions required to complete a specific work objective. โ Job Hazard Analysis (JHA). Answer: The process of evaluating a specific task (job) to identify all hazards or potential hazards that the individuals performing the job (task) may be exposed to. โ Joint Health and Safety Committee (JHSC). Answer: A group comprised of management and worker representatives that work together to identify deficiencies in the safety management system, and then recommend solutions to correct identified deficiencies. The JHSC plays a key role in the development, implementation, and maintenance of a health and safety program. โ Lagging Indicators. Answer: Measure the end result of OHS processes, policies and procedures. They're a record of things that have already happened. Since they record things after the fact, they inform a reactive health and safety culture. โ Leading Indicators. Answer: Focus on future health and safety performance with the intent of continuous improvement. They are a signal and monitor of what is being done on an ongoing basis to prevent worker illness and injury.
โ Lockout. Answer: A positive method for disconnecting power, or making machinery, equipment or a process inoperative. Normally, this is done with locks attached to electrical plugs, breakers or switches, control units, valves, or levers. The person placing the lock at the lockout point must be identified.

Part I of the Hazardous Products Act. Restricted products that are packaged in sizes appropriate for the general public, labelled as required by the Consumer Packaging and Labelling Act and offered for sale in ordinary retail outlets are considered, for the purposes of WHMIS, to be "consumer products." โ Root (Basic) Causes. Answer: The deficiencies in carrying out safety policies, programs, plans, processes, procedures or practices that allowed the intermediate and immediate causes to exist. Root causes are often the result of: Inadequate system to control hazards through activities such as safety leadership, training, planned inspections, maintenance, hazard analysis and procedures, incident investigation and analysis, emergency preparedness, and/or rules and procedures.
