Worksite Analysis

Conducting a Worksite Analysis

Worksite analysis is a continuous process.

As part of the deployment process, it's important to make sure the CSMS is working effectively. To do that conduct regular worksite analyses to analyze and evaluate the performance (results). Conduct systematic actions that provide information as needed to recognize and understand the hazards that exist and work practices used on each worksite.

Listed below are types of worksite analysis actions that can assist you with making an inventory of potential and actual hazards in your worksite:

• Job safety analysis.
• Comprehensive hazard surveys (insurance inspections, OSHA consultation, etc.).
• Hazard analysis of changes in your worksite (new equipment, new processes
• Regular site safety inspections (employee and management).
• Employee report of hazards or potential hazards.
• Injury and illness trend analysis.
• Personal protective equipment assessment.
• Ergonomic analysis.
• Specific identification of confined spaces.
• Identification of energy sources for specific machines.
• Copies of written inspections and surveys by: fire department, in-house as required by Safety standards (e.g., overhead crane inspections, powered industrial truck daily inspection, etc.).

OSHAcademy courses 702, 704, 706, 707, 709, 710, and 711 cover these topic areas.

Analyzing a Construction Worksite

Each of the following program components should be analyzed on the worksite. Use a checklist to help make sure your analysis is efficient and accurately identifies hazards. Be sure to document what you find whether it is in conformance or not.

Recognized and Foreseeable Hazards

In conducting the worksite analysis, it’s important to look for hazards that are generally recognized within the industry, and those hazards that should be foreseeable on the worksite.

"Recognized" Hazards

As described in OSHA's Field Operations Manual, recognition of a hazard is established on the basis of industry recognition, employer recognition, or "common sense" recognition criteria.

• Industry Recognition: A hazard is recognized if the employer's industry recognizes it. Recognition by an industry, other than the industry to which the employer belongs, is generally insufficient to prove industry recognition. Although evidence of recognition by the employer's specific branch within an industry is preferred, evidence that the employer's industry recognizes the hazard may be sufficient.
• Employer Recognition: A recognized hazard can be established by evidence of actual employer knowledge. Evidence of such recognition may consist of written or oral statements made by the employer or other management or supervisory personnel
• Common Sense Recognition: If industry or employer recognition of the hazard cannot be established, recognition can still be established if it is concluded that any reasonable person would have recognized the hazard. This argument is used by OSHA only in flagrant cases. Note: Throughout our courses we argue that "common sense" is a dangerous concept in safety. Employers should not assume that accidents in the worksite are the result of a lack of common sense.

"Foreseeable" Hazards

An important, and potentially difficult, question to ask about the nature of worksite hazards relates to whether they are "foreseeable." The question of foreseeability should be addressed by safety managers during the worksite analysis. A hazard for which OSHA issues a citation must be reasonably foreseeable. However, all the factors which could cause a hazard need not be present in the same place at the same time in order to prove foreseeability of the hazard.

Example: If sufficient quantities of combustible gas and oxygen are present in a confined area to cause an explosion if ignited, but no ignition source is present or could be present, no OSHA duty clause Section 5(a)(1) violation would exist. However, if the employer has not taken sufficient safety precautions to preclude the presence or use of ignition sources in the confined area, then a foreseeable hazard may exist. NOTE: It is necessary to establish the reasonable foreseeability of the workplace hazard, rather than the particular circumstances that led to an accident/incident. (Source: FOM)

New Equipment and Processes

Designate a competent person to analyze new equipment, processes, procedures and materials on the worksite for hazards and potential hazards at your companies work sites. Document the findings and develop plans to minimize or design out the hazards using the "hierarchy of control" strategies. (More on the HOC in the next module.)

Job Hazard/Safety Analysis

A Job Hazard/Safety Analysis (JSA) should be used to determine potential hazards and identify methods to reduce exposure to the hazards at your work sites. (See Course 706, Job Hazard Analysis, for more on this topic).

Job Safety Analysis is a method of planning for safety. There are three basic parts to a JSA.

• The first component of a JSA is breaking down a job or task into the specific steps it takes to complete the job. Although this can be done in small detail, typically only the major steps are listed. This often results in five to ten steps. The steps are listed in chronological order, listing the first thing that should be done, then what comes next, and so on.
• The second component of a JSA is to list all the hazards that are involved in each step. There may be many hazards that get listed next to some steps and may not be any associated with some steps.
• The third step is to write down how each hazard will be eliminated or controlled. In other words, describe what needs to be done in order to perform that task safely.

Note: Job Hazard Analysis is often called different things. Other names for it include: job hazard analysis, job task analysis, task hazard analysis, safe work procedure, and safety task analysis.

Employee Hazard Reports

Employees play a key role in identifying, controlling, and reporting hazards that may occur or already exist in your worksite. Employee reports of potential hazards can be an effective tool to trigger a closer look at a piece of equipment, operation, or how work is being performed. Reports of potential hazards can also provide suggestions to eliminate a hazard. They can also help to determine if any trends in hazardous conditions or unsafe behaviors exist.

Observation Processes

An informal observation process is nothing more than being watchful for hazards and unsafe behaviors throughout the work shift. No special procedure is involved. All employees should be expected to look over their work areas once in a while.

One of the most effective proactive methods to collect useful data about the hazards and unsafe behaviors at the worksite is the formal observation program because it includes a written plan and procedures.

For example, safety committee members or other employees may be assigned to complete a minimum number of observations of safe/unsafe behaviors during a given period of time. This data is gathered and analyzed to produce graphs and charts reflecting the current status and trends in employee behaviors.

Posting the results of these observations tends to increase awareness and lower injury rates. But, more importantly, the data gives valuable clues about safety management system weaknesses.

Observation is important because it can be a great tool to effectively identify behaviors that account for fully 95 percent of all worksite injuries. The walkaround inspection, as a method for identifying hazards, may not be as effective as observation in identifying unsafe behaviors.

Worksite Safety Inspections

Inspections are the best understood and most frequently used tool to assess the worksite for hazards. Much has been written about them, and many inspection checklists are available in various OSHA publications. The term "inspection" means a general walkaround examination of every part of the worksite to locate conditions that do not comply with safety standards. This includes routine industrial hygiene monitoring and sampling.

Inspection Frequency

The regular site inspection should be done at specified intervals. The employer should inspect as often as the type of operation or character of equipment requires.

The inspection team can document in writing the location and identity of the hazards and make recommendations to the employer regarding correction of the hazards. Regular inspections of satellite locations should be conducted by the committee team or by a person designated at the location.

The frequency of a safety inspection depends on the nature of the work being performed and the worksite. More frequent change and higher probability for serious injury or illness require more frequent inspections. For construction sites, daily inspections are a must because of the rapidly changing nature of the site and its hazards.

At small fixed worksites, the entire site should be inspected at one time. And even for the smallest worksite, inspections should be done at least quarterly. If the small worksite uses hazardous materials or involves hazardous procedures or conditions that change frequently, inspections should be done more often.

Incident and Accident Investigation

Your company should conduct an investigation for all injury accidents, property-damage incidents and non-injury near misses. Be sure to adequately document all reports. Only those who are properly trained and trusted should conduct investigations involving injury or property damage.

The primary goal of conducting an investigation is to determine the "root cause(s)," or system weakness in the "6-Ps" of the CSMS: plans, programs, policies, processes, procedures and practices. Uncovering the root causes will best help to prevent the risk of future incidents and accidents on the worksite.

Investigation reports should help determine injury and illness trends over time, so that patterns with common root causes can be identified and prevented. Investigations should not place blame.

Accidents and "near-miss" incidents should be investigated by qualified and trained persons in your company. It's important that the person also be one who is trusted by employees. The reports should be reviewed by the executive in charge your company (or the person in your company that has the power and ability to address the findings of the report) and the Safety Committee within a specified amount of time after an accident/incident. (More on this topic in course 702, Effective Accident Investigation).
