What are the two aspects of the machine safety and health program?
Guards and training
What are the purpose of/modes of guards
evaluating machine energy and movement hazards present during normal production, servicing and maintenance hsall address machine hazards through: guarding, lockout/tagout, periodi visual checks of guards, investigation/notification
What is covered under training for machine safety and health program
lockout/tagout, employee responsibilities under and the elements of MSHP, presented in a proficient language, and retrain as needed
General description of risk
as frequency goes up , consequence goes down. There is a line of acceptabiliy
System safety definition
formal engineering discipline and process for identifying and controlling hazards, and the risk associated with these hazards
Second Law of Thermodynamics
entropy of any isolated system always increases. isolated systems spontaneously evolve towards thermal equilibrium. BASICALLY the entropy of the universe only increases
Definition of Hazard analysis
the basic key component of the system safety process.
Levels of Risk severity on risk assessment matrix
High, serioius, medium, low, eliminated
Axis on risk assesment matrix
probability and severity
True/False: Absolute safety is not possible because complete freedom from all hazardous conditions is not always possible
True. particularly when dealing with complex inherently hazardous systems
True/False: The objective becomes to develop a system with no mishap risk
False: realistic objective becomes that of developing a system with acceptable mishap risk
System safety requires that….
risk be evaluated, and the level of risk accepted or rejected by an appropriate decision authority
Fundamental objective of system safety is to
identify, eliminate or control, and document system hazards. Cradle to grave
Heirarchy of Hazard Control
Avoidance Eliminate Substitution Engineering Controls Warning Administrative Control PPe
Three types of risk in engineering systems
- Were acceptable at the time of design or in the work plan
- Risks that come from abnormal conditions
- Risks associated with design or planning errors
Risk assessment techniques attempt to
identify (causes of failure), rate, establish(conditions udner which the failure has greatest likelihood of occurance and/or gravest consequence)
Ways to treat risk
Avoidance Mitigation Transfer (Insurance) Acceptance Ignore (UFO)
True of false: Proactive preventative approaches to safety during design process is more cost-effective
True.
Define DFS
Design for safety is a process that utilizes the system safety process ot intentionally design-in safety. Anticipates and eliminates
Define SSP
System safety program is a formal approach to eliminate hazards through engineering, design, education, management policy, and supervisory control of conditions and practices.
What are the three layers in evaluating a system
the system
your lens
the information
What is the goal of system safety
The protection of life, systems, equipment, and the environment
What is the objective of system safety?
elimination of hazards that can result in death, injury, system loss, and damage to the environment. If not eliminate, reduce risk of mishap through design control measures
How is reducing mishap risk achieved?
reducing the probability of the mishap and/or severity of the mishap
