Accident/incident investigation ✔Correct Answer-Although reactive it is another tool for
uncovering hazards and management system failures. 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.
Brain Storming ✔Correct Answer-A free flowing group discussion by employees who perform
a task to identify hazards, risks and solutions.
Job Safety (Hazard) Analysis ✔Correct Answer-A method that can be used to identify, analyze
and record the steps involved in performing a specific job; the existing or potential safety and
health hazards associated with each step; and the recommended action(s)/procedure(s) that
will eliminate or reduce these hazards and the risk of a workplace injury or illness.
Trend Analysis ✔Correct Answer-Worksite analysis is analysis of injury and illness trends over
time, so that patterns with common causes can be identified and prevented. Review 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.
What if ✔Correct Answer-For relatively uncomplicated processes, review the process from
raw materials to product. At each handling or processing step, "what if" questions are
formulated and answered , to evaluate the effects of component failures or procedural errors
on the process.
Checklist ✔Correct Answer-For more complex processes, the "what if" study can be best
organized through the use of a "checklist" and assigning certain aspects of the process to the
comittee members having the greatest experience or skill in evaluating those aspects. Operator
practices and job knowledge are audited in the field, the suitability of equipment and materials
of construction is studied, and the chemistry of the process of control systems are reviewed,
and the operating and maintenance records are audited. Generally, a checklist evaluation
process precedes use of the operated safely for many years and has been subjected to periodic
and thorough safety inspections and audits.
What if/Checklist ✔Correct Answer-Is a broadly based hazard assessment technique that
combines the creative thinking of a selected team of specialists with the methodical focus of a
prepared checklist. The result is a comprehensive hazard analysis that is extremely useful in
training operation personnel on the hazards of the particular operation.
,Failure modes and effect analysis (FMEA) ✔Correct Answer-System analysis technique that
identifies the manner in which failures occur and investigates their impact on one another, as
well as on other parts of the system.
Fault-tree analysis ✔Correct Answer-System safety technique using deductive (general to
specific) analysis that starts with an undesired event and analyzes the way the undesired event
can occur. Uses Boolean algebra to simplify the fault-tree diagram to a minimal cut set, which is
the shortest, most direct path that allows an event to take place.
Hazard and operability study ✔Correct Answer-Study used to identify problems associated
with potential hazards and deviations in plant operations from the design specifications and is
carried out by multidisciplinary team following a structure that includes a series of guide words.
Management oversight and risk tree (MORT) ✔Correct Answer-Analytical system that
develops a logic tree to identify total system risks, both those inherent in physical equipment
and processes and those arising from operational/management inadequacies.
Preliminary hazard analysis ✔Correct Answer-System safety technique that is the initial effort
to identify potentially hazardous components within a system during the design phase.
Systems Hazard Analysis (SHA) ✔Correct Answer-Method that seeks to identify physical and
functional incompatibilities between adjacent, interconnected, and interacting elements.
System safety engineering report ✔Correct Answer-Report that consists of a compliation of
the production phase inputs that identifies and documents the hazards of the final product or
system and provides definite conclusions about the safety integrity of the product and the
manner in which hazards have been controlled.
System safety program plan ✔Correct Answer-Plan that identifies the task to be accomplished
in the total safety program for the evolution of the system and is considered the key to a
successful program.
Technique of human rate error prediction ✔Correct Answer-System safety technique that
calculates the probability of human operating errors.
Equipment and machinery manufacturers ✔Correct Answer-Owner and operator manuals
typically include (1) warnings of hazards that may be present during operation and instructions,
and (2) precautions for safely operating the equipment or machinery.
Chemical manufacturers ✔Correct Answer-Are required to provide downstream users with
safety data sheets. These summarize information about health hazards, and provide instructions
on how to safely handle and use the chemical.
, Trade associations, insurance carriers, manufacturers and gov. agencies. ✔Correct Answer-
Some trade associations and insurance carriers publish safety and health information. Some
manufacturers, and government agencies such as OSHA, the National institute for occupational
safety and health (NIOSH), issue safety and health warnings and hazard alerts directed toward
particular products, work practices, or hazards.
Employee safety and health complaints ✔Correct Answer-Employees have first-hand
familiarity with the hazards at their workplace. Any prior or recent complaints about safety and
health conditions, whether formal or informal, point to potential safety and health hazards.
Medical surveillance activities and employee exposure data. ✔Correct Answer-These results
can alert employers to hazards posed by chemical, physical, and biological agents. Use of
aggregated results is important to maintain the confidentiality of employee medical
information.
Disaster preparedness scenarios ✔Correct Answer-Conducting a "what-if" analysis of possible
natural and man made disasters can help identify hazards that have a low probability of
occurrence, but that may have disastrous consequences. Examples include explosions that could
be caused by flammable chemicals or combustible dust, hazards that may be created by strong
weather phenomena, or incidents related to a criminal or terrorist act.
Chemical Agents ✔Correct Answer-Safety Data sheets (SDS) provide a good basis for
developing a list of toxic chemicals in the workplace. When many chemicals are present,
hazards of the following types of chemicals should be determined first: chemicals that are (1)
volatile (2) handled or stored in open containers; (3) used in processes where employees are
likely to be exposed through inhalation, ingestion, or skin contact; or (4) flammable and stored
or used in a manner that poses a fire or explosion hazard.
Biological agents ✔Correct Answer-These include bacteria, viruses, fungi, and other living
organisms that can cause acute and chronic infections by entering the body either directly or
through breaks in the skin. Sources can include laboratory operations, fermentation processes,
or handling of raw food products. They also include exposure to blood or other body fluids or to
clients or patients with infections diseases.
Physical agents ✔Correct Answer-These include excessive levels of ionizing and nonionizing
electromagnetic radiation, noise, vibration, illumination, and temperature.
Equipment operation ✔Correct Answer-Ideally, each piece of equipment will be inspected to
ensure that all safeguards necessary to protect employees are in place and effective. These
include measures to ensure that employees avoid becoming caught in or struck by equipment;
burned on hot surfaces; shocked through contact with energized parts of electric circuits.
Important areas of focus for equipment inspection include equipment guarding; the condition
of moving parts, parts that support weight, and brakes; and hazards that might arise during
maintenance activities.
