Published by SALUSIn safety documentation, a task is the specific unit of work being performed within a job. It should be defined clearly enough that the work can be broken into steps, the hazards in each step can be identified, controls selected, and a safe procedure written. A job hazard analysis (JHA) is the common method for doing this: it "breaks a job down into tasks; each task is evaluated to determine if there is a better, safer way to do it." [1]
A complete task definition in safety documentation typically includes the following elements:
- Task description: the job/task title, location, date or identifier, and a concise description of what work is being done.
- Job task analysis: the task is divided into sequential steps so each part of the work can be reviewed.
- Hazard identification: each step is examined for hazards such as struck-by, caught-in/between, falls, overexertion, contact hazards, and overexposure.
- Risk assessment: evaluate the likelihood and severity of harm for each hazard and prioritize higher-risk tasks or exposures for control.
- Preventive measures and controls: identify engineering controls, administrative or management controls, PPE, and any interim measures.
- Safe work procedure: document the required safe method for performing the task step by step.
- Regulatory requirements: identify any task-specific OSHA/Cal/OSHA/Oregon OSHA requirements, exposure limits, permits, training, monitoring, recordkeeping, and competent-person or supervisor requirements that apply.
[1] [2] For the task description portion, document enough detail so the work is unambiguous: what is being done, where, by whom or what trade, the equipment or materials involved, and the boundaries of the assignment. Good documentation usually includes the job/task title, location, step descriptions, hazards, and preventive measures. For some regulated activities, the assigned task or job must also be identified on formal permits or records. [2] [10]
A job task analysis / job hazard analysis is the structured review of how the task is performed. The normal sequence is to prepare by reviewing incident history and involving employees, observe the task, list each step, identify hazards at each step, assess risk, select controls, and then write the safe job procedure. JHAs are especially useful for complex work, work with difficult-to-control hazards, and work with a history of incidents or near misses. [1] [1]
Hazard identification means identifying the sources of potential injury, illness, or exposure associated with each task step. In construction documentation, hazards are often categorized by mechanism of injury or exposure, such as struck-by, contact-with, caught-between, falls, overexertion, and overexposure. For regulated health hazards, hazard identification should also recognize substance-specific exposures such as respirable crystalline silica or lead. [1] [4] [6]
Risk assessment is the evaluation of the identified hazards to determine how serious the harm could be, how likely it is to occur, and which tasks need priority controls. In practice, this means considering exposure duration, frequency, number of workers exposed, work environment, and whether the task is routine, complex, or changing. Where a standard requires exposure assessment, that assessment becomes part of the risk assessment process. [1] [8] [6]
Safe work procedures are the written instructions that specify the safest approved way to perform the task. They should translate the JHA into action by stating the sequence of work, required controls, PPE, equipment conditions, hold points, and what to do if conditions change. For many exposure-driven tasks, the procedure must incorporate the exact engineering controls and work practices required by the applicable standard. [1] [7] [5]
Applicable regulatory safety requirements depend on the task. Safety documentation should identify the governing standard, the required controls, any exposure limits, training, permits, competent-person or supervisor requirements, and required records. Examples from the provided sources include confined-space entry permits, silica task-specific controls, lead exposure assessment, and documentation of objective data or monitoring records. [10] [8] [6] [9]
Some standards also define who must oversee or authorize task safety. A competent person is someone capable of identifying existing and predictable hazards and authorized to take prompt corrective measures. In other contexts, a trained supervisor or entry supervisor must authorize or control the task. This matters because the task definition should identify who is responsible for hazard recognition, authorization, and corrective action. [3] [10] [6]
In practical terms, a strong task definition in safety documentation should answer: What exact work is being done? What are the steps? What can go wrong at each step? How severe and likely is the harm? What controls are required before and during the work? Who is authorized and competent to oversee it? What permits, exposure assessments, monitoring, training, and records are required by regulation?
A concise model definition is: A task is a clearly defined unit of work within a job, described by its location, purpose, steps, equipment, materials, and personnel, and documented so that hazards can be identified, risks assessed, controls selected, safe work procedures written, and applicable regulatory requirements implemented and verified.

# THE ABCS OF CONSTRUCTION SITE SAFETY (cont.) ## Safety committees – Division 1, [redacted phone](7) (cont.) THE ABCS OF CONSTRUCTION SITE SAFETY Job Hazard Analysis Job hazard analysis - or JHA - is an industry best practice method of identifying, assessing, and controlling hazards associated with a specific job. A JHA breaks a job down into tasks; each task is evaluated to determine if there is a better, safer way to do it. A job-hazard analysis works well for jobs with difficult-to-control hazards and jobs with histories of accidents or near misses. JHAs for complex jobs can take a considerable amount of time and expertise to develop. You may want to enlist the help of a safety professional. Most Oregon OSHA rules do not specifically require a JHA. However, employers are required to take the necessary steps to ensure that jobs are safe and healthful. A JHA helps fulfill this requirement. Employers applying for Oregon OSHA's Safety and Health Achievement Recognition Program (SHARP) and the Voluntary Protection Program (VPP) conduct JHAS. Key steps in a JHA: . Prepare: Review accident histories, involve employees, conduct risk assessment, and prioritize jobs based on hazardous exposures. Often, jobs need to be broken into tasks to better analyze the steps involved. - Observe the task and list the steps required to accomplish it. • Identify hazards in each step. . Categorize hazards into the following types: struck-by, struck-against, contact-by, contact-with, caught-on, caught-in, caught-between, fall-to-surface, fall-to-below, overexertion, bodily reaction, and overexposure. • Develop hazard controls (engineering controls, management controls, personal protective equipment (PPE), and/or interim measures). • Write a safe job procedure. 26
