A Review of Commonly-UsedPerformance IndicatorsBy Jerome E. Spear, CSP, CIH, FAIHA How an organization measures performance undoubtedly influences organizational behavior. However, measuring safety is difficult because it is difficult to predict the impact that new safety metrics will have on individual behavior, attitudes, and the overall safety climate. Regardless of how difficult it is to…

After determining worker exposure to noise, intervention may be needed to reduce noise exposures to allowable levels. There are three general ways to reduce to noise exposure, which are as follows (in order of preference): • Engineering Controls • Administrative Controls • Personal Protective Equipment (PPE) When engineering controls are not feasible to reduce exposures,…

Case 1: A 28-year old construction worker was holding onto a steel ladder being moved by a telescoping boom crane. As the crane’s boom was swung in the direction of 7,200 volt power lines, the cable contacted the lines and the worker was electrocuted. Case 2: A co-owner of a steel erection company and three…

National estimates suggest that about 10 times as many fatal occupational illnesses occur compared with fatal occupational injuries.¹ Furthermore, one study concluded that the risk of developing an occupationally-related disease over a lifetime in a construction trade is two to six times greater than for non-construction workers.² For various reasons, awareness and efforts to manage…

Factors Affecting Rated Capacity The first step in creating a lift plan is to understand the factors affecting the strength and stability of mobile cranes. Some of these factors are described below. Machine configuration. Load chart ratings may only be applied if the machine is rigged according to the manufacturer’s specifications. Some questions to consider…

By Jerome E. Spear, CSP, CIH From 2011 to 2015, the Census of Fatal Occupational Injuries (CFOI) reported 220 total crane-related deaths, an average of 44 per year over this five-year period (CFOI, 2017). A 2009 study by The Center to Protect Workers’ Rights examined the causes of crane-related deaths based on data obtained from…

A few years ago, I investigated an incident involving a fire that resulted from the transfer of a flammable liquid mixture. A driver of a chemical supplier was delivering a load of product to a customer. The product consisted of a solvent solution containing toluene and other flammable ingredients. As the driver was filling a 350-gallon…

BY JEROME SPEAR, CSP, CIH • J.E. SPEAR CONSULTING, LP An industrial hygiene exposure assessment is the process used to evaluate a person’s exposure to a chemical or physical agent. However, in order to measure a worker’s “actual” exposure, a monitor would be required to be placed in his/her breathing zone each and every day,…

By Jerome E. Spear, CSP, CIH OSHA requires employers to determine Cr(VI) exposures to employees. Options for exposure determinations include initial and periodic exposure monitoring and/or the use of objective data. If objective data is used, the data must reflect workplace conditions closely resembling the processes, types of material, control methods, work practices, and environmental…

By Jerome E. Spear, CSP, CIH According to the Occupational Safety and Health Administration (OSHA), one death occurs in every 10 confined space accidents. Injuries and fatalities involving confined spaces often involve successive fatalities when “would-be” rescuers succumb to the same problem as the initial victim. Almost every kind of industry has some type of…
