Worksite Analysis
What's a worksite analysis and how often should it be done?
Worksite analysis involves a variety of worksite examinations to identify not only
existing hazards, but also conditions and operations in which changes
might create hazards. Effective management actively analyzes the work
and the worksite, to anticipate and prevent harmful occurrences.
Here’s a suggested plan to identify all worksite hazards:
- Conduct a comprehensive, baseline survey for safety and health and periodic, comprehensive update surveys.
- Change analysis of planned and new facilities, processes, materials, and equipment.
- Perform routine job hazard analyses.
- Conduct periodic and daily safety and health inspections of the workplace.
These four major actions form the basis from which good hazard prevention and control can develop.
Comprehensive surveys
For small businesses, OSHA-funded, state-run consultation services can
conduct a comprehensive survey at no cost. Many workers’ compensation
carriers and other insurance companies offer expert services to
help their clients evaluate safety and health hazards. Numerous
private consultants provide a variety of safety and health expert
services. Larger businesses may find the needed expertise at the
company or corporate level.
For the industrial hygiene survey, at a minimum, all chemicals and hazardous
materials in the plant should be inventoried, the hazard communication
program should be reviewed, and air samples analyzed. For many industries,
a survey of noise levels, a review of the respirator program, and
a review of ergonomic risk factors are needed.

Change Analysis
Anytime something new is brought into the workplace, whether it be a piece
of equipment, different materials, a new process, or an entirely
new building, new hazards may unintentionally be introduced. Before
considering a change for a worksite, it should be analyzed thoroughly
beforehand. Change analysis helps in heading off a problem before
it develops.
You may find change analysis useful when:
- Building or leasing a new facility.
- Installing new equipment.
- Using new materials.
- Starting up new processes.
- Staffing changes occur.

Hazard Analysis
Hazard analysis techniques can be quite complex. While this is necessary
in some cases, frequently a basic, step-by-step review of the operation
is sufficient. One of the most commonly used techniques is the Job
Hazard Analysis (JHA). Jobs that were initially
designed with safety in mind may now include hazards or improper
operations. When done for every job, this analysis periodically
puts processes back on the safety track.
Other, more sophisticated techniques are called for when there are complex
risks involved. These techniques include: WHAT-IF Checklist, Hazard
and Operability Study, Failure Mode and Effect Analysis, and Fault
Tree Analysis.

Safety and Health Inspections
Routine site safety and health inspections are designed to catch hazards
missed at other stages. This type of inspection should be done at
regular intervals, generally on a weekly basis. In addition, procedures
should be established that provide a daily inspection of the work area.
You can use a checklist already developed or make your own, based on:
- Past problems.
- Standards that apply to your industry.
- Input from everyone involved.
- Your company's safety practices or rules.
Important things to remember about inspections are:
- Inspections should cover every part of the worksite.
- They should be done at regular intervals.
- In-house inspectors should be trained to recognize and control hazards.
- Identified hazards should be tracked to correction.
Information from inspections should be used to improve the hazard prevention and control program.

Catching Hazards that Escape Controls
After hazards are recognized and controls are put in place, additional analysis
tools can help ensure that the controls stay in place and other hazards
don’t appear. These other tools include:
- Employee reports of hazards.
- Accident and incident investigations.
- Injury and illness trend analysis.
Employee Reports of Hazards
Employees play a key role in discovering and controlling hazards that may develop
– or that already exist – in the workplace. A reliable system for employee
reporting is an important element of an effective safety and health system.
The workplace must not only encourage reporting, but must value it.
It is often helpful to establish multiple ways to report hazards so that, depending
on comfort level and the nature of the issue, there are several avenues
to get concerns addressed. Examples include: supervisor chain of command,
safety and health committee member, voice mail box and a suggestion box.
An effective reporting system needs:
- A policy that encourages employees to report safety and health concerns,
- Timely and appropriate responses to the reporting employee,
- Timely and appropriate action where valid concerns exists,
- Tracking of required hazard correction,
- Protection of reporting employees from any type of reprisal or harassment.
Accident/Incident Investigations
Accident/incident investigation is another tool for uncovering hazards that were missed
earlier or that slipped by the planned controls. But it’s only useful
when the process is positive and focuses on finding the root cause, not
someone to blame!
All accidents and incidents should be investigated. "Near-misses" are considered an
incident, because, given a slight change in time or position, injury or
damage could have occurred.
Six key questions should be answered in the accident investigation and report: who, what,
when, where, why, and how. Thorough interviews with everyone involved
are necessary.
The primary purpose of the accident/incident investigation is to prevent future occurrences.
Therefore, the results of the investigation should be used to initiate
corrective action.
Trend Analysis
The final action recommended under Worksite Analysis is analysis of injury
and illness trends over time, so that patterns with common causes can
be identified and prevented. Review of the OSHA injury and illness forms
is the most common form of pattern analysis, but other records of hazards
can be analyzed for patterns. Examples are inspection records and employee
hazard reporting records.
- Injury and Illness Records Analysis:
- Since there must be enough information for patterns to emerge, small sites may require
a review of 3-5 years of records. Larger sites may find useful trends yearly, quarterly, or monthly.
- When analyzing injury and illness records, look for similar injuries and illnesses.
These generally indicate a lack of hazard controls. Look for where the
injury or illness occurred, what type of work was being done, time of
day, or type of equipment.
- Analysis of Other Records:
- Repeat hazards, just like repeat injuries or illnesses, mean that controls
are not working. And, patterns in hazard identification records can
show up over shorter periods of time than accidents or incidents. Upgrading
a control may involve something as basic as improving communication
or accountability.
Hazards found during worksite
analysis should be reviewed to determine what failure in the safety and health system
permitted the hazard to occur. The system failure should then be corrected to ensure that
similar hazards do not reoccur.
