Benchmarking and Performance Criteria
For a moment, let’s try to evaluate human behavior while driving a motor vehicle. Is it even possible to
capture the multitude of behaviors, attitudes, stresses, tensions and mental pre-occupation present in an individual prior to turning on the ignition? How does one even attempt to design the controls and informational displays to enhance the capabilities and operability of the vehicle to enhance safety? How much does that cost? Is it worth it? Doesn’t the operator have a responsibility for assuring safe driving practices?
For fall protection systems, certification can mean the difference between life and death for a worker at
heights. No matter how old a fall protection system is, its sole purpose is to save a falling worker. Whether you’ve just installed new systems, or you’re evaluating existing systems, you need to be confident that they will work properly. This article explains the elements that must be in place to achieve a certified system.
Design and planning priorities for utility, productivity and immediate return can obscure the vision that many hazards can be removed before construction begins. Technology is available to easily incorporate safety as an overriding priority to protect the consumer, user, operator and construction workers from injuries. However, without the application of this technology, safety is often relegated to a function of the user, operator or consumer.
This paper presents a safety assessment methodology based on STPA (a systems-theoretic hazard
analysis); the assessment methodology provides an organized, methodical, and effective
means to assess safety risk and develop appropriate hazard mitigations regardless of where
in the life cycle the assessment is started.
A PowerPoint presentation covering the system safety approach to fire risk assessments. A five step fire risk assessment procedure is covered.
Poor safety performance is a consequence of engineering design that fails to fully consider human interaction in the system. Engineers play a critical role in proactively designing jobs and equipment with low ergonomic risk, as well as reactively reducing existing exposures in the workplace. Therefore, to not have site engineers participate in your site ergonomics initiative puts you at an immediate disadvantage.
Inherently safer design (ISD) is a philosophy for addressing safety issues in the design and operation of facilities that use or process hazardous chemicals. When considering ISD, the designer tries to manage process risk by eliminating or significantly reducing hazards. Where feasible, ISD provides more robust and reliable risk management, and has the potential to make the chemical processing technology simpler and more economical by eliminating the need for expensive safety systems and procedures.
On Dec, 16, 2011, a 28-year-old male temporary worker (victim) was fatally injured while cleaning and sanitizing a double auger screw conveyor machine (feed pump skid). The victim was reportedly cleaning the machine’s tub while the machine’s double augers were rotating. Both of the victim’s arms became caught in the double augers and he was pulled into the machine. A co-worker heard the victim yell, saw the victim being pulled in and stopped the machine with the emergency stop. Another co-worker ran to call emergency medical services (EMS). Personnel from the local and state police departments, fire department and EMS all arrived after the calls.
EHS professionals are facing increased pressure to diversify their skills and develop new risk assessment techniques. A small size company requested a new product risk assessment and hazard evaluation. The product is intended for export to the European Union and had to meet international standards. On the other hand, the product is manufactured in the USA and the management wanted to implement PtD principles. The authors developed new tools and successfully implemented the new PtD model to evaluate the product.
Electricity is the most common commodity for business operations, yet it is the least understood of all processes. An infrastructure failure that results in a loss of electrical service can have devastating consequences.
The Body of Knowledge project is dedicated to creating a living reference that represents the collective knowledge of the Safety, Health and Environmental profession. While the preliminary work has begun, there is still more to do. The purpose of this website is to introduce subject areas that will eventually be part of the Body of Knowledge, and to gather feedback on the future direction, and ongoing assessment of what needs to be completed.
