Communicating Severity Of Hazard With The Signal Word On A Safety Sign, Roger C. Jensen, Andrew M. Mccammack Jan 2004

Communicating Severity Of Hazard With The Signal Word On A Safety Sign, Roger C. Jensen, Andrew M. Mccammack

Safety Health & Industrial Hygiene

An experiment examined five signal words on safety signs for effectiveness at communicating information about severity of a hazard. Perceived severity was rated by 59 college students for the signal words Deadly, Danger, Warning, Caution, and Notice. Results indicated that Deadly communicated the highest ratings for severity. Danger was second. Warning and Caution were tied for third. The lowest ratings were for Notice.


Comparison Of Student Versus Employee Test Populations For Warning Sign Research Based On Severity Ratings For Signal Words, Scott Thomas, Roger C. Jensen Jan 2004

Comparison Of Student Versus Employee Test Populations For Warning Sign Research Based On Severity Ratings For Signal Words, Scott Thomas, Roger C. Jensen

Safety Health & Industrial Hygiene

Most studies of warning signs involve undergraduate students as subjects. This paper reports a direct comparison of findings from an undergraduate population and an employed population. The 48 employed subjects from this study were compared with 59 undergraduate subjects from a companion study. Subjects from both populations were shown the same signs and asked to rate the severity level connoted by each sign. The signs differed only in signal word. Results for each population indicated that signal word had a highly significant effect on severity ratings. When the two populations were compared for ratings of each signal word, the only …


Severity Message From Hazard Alert Symbol On Caution Signs, Roger C. Jensen, Andrew M. Mccammack Jan 2003

Severity Message From Hazard Alert Symbol On Caution Signs, Roger C. Jensen, Andrew M. Mccammack

Safety Health & Industrial Hygiene

Standards for the design of signal word panels specify different combinations of colors, signal words, and a hazard alert symbol. The warning sign standards of the American National Standards Institute specify a yellow signal word panel, with the word Caution and a hazard alert symbol, for signs marking people hazards. The same panel, without the symbol, is intended for property hazards. The purpose of this study was to determine if the presence or absence of the symbol effectively conveys the intended severity messages. A sample of 59 college students rated their impressions of a Caution sign with and without the …


Effectiveness Of Colors Used On Safety And Health Signs For Communicating Severity Of Injury, Andrew M. Mccammack, Roger C. Jensen Jan 2002

Effectiveness Of Colors Used On Safety And Health Signs For Communicating Severity Of Injury, Andrew M. Mccammack, Roger C. Jensen

Safety Health & Industrial Hygiene

Signs are used extensively in workplaces and on products to identify hazards and provide instructions for appropriate behavior. A fundamental element of these signs is the signal-word panel located at the top of the sign. The colors and words in this panel are intended to convey information about the hazard identified. One type of hazard information concerns the severity of injury/illness associated with the hazard. The standard of the American National Standards Institute (ANSI) for facility signs uses three severity categories: 1) death or serious injury, 2) minor or moderate injury, and 3) property damage. The standard specifies which signal-word …


Case Study Of An Ergonomics Training Program For Nursing Home Workers, Roger C. Jensen Jan 2002

Case Study Of An Ergonomics Training Program For Nursing Home Workers, Roger C. Jensen

Safety Health & Industrial Hygiene

This paper describes a case study of a labor-based ergonomics-training program that makes use of some effective worker training methods. The program focus was on ergonomics awareness and back injury prevention for nursing home workers. It was developed and conducted by a not-for-profit organization affiliated with the Service Employees International Union. Training methods included the train-the-trainer model and the small group activity method. The investigation also compared the program components with those identified by the Occupational Safety and Health Administration (OSHA) as being key elements in effective safety training.


Safety And Health Sign Colors And Signal Words For Communicating Information On Likelihood And Imminence Of Threat, Roger C. Jensen, Andrew M. Mccammack Jan 2002

Safety And Health Sign Colors And Signal Words For Communicating Information On Likelihood And Imminence Of Threat, Roger C. Jensen, Andrew M. Mccammack

Safety Health & Industrial Hygiene

Signs are used extensively in workplace facilities and on products to identify hazards and provide instructions and safety information. A fundamental component of these signs is a signal-word panel located at the top of the sign. Certain colors and signal words in this panel are intended to convey information about a hazard, including likelihood of harm and imminence of the threat. The purpose of this study was to determine if young adults without prior training on safety signs associate signal words and color with likelihood of harm and imminence of the threat. The sample population consisted of 59 college students. …


Alertness-Supporting Activities For Control Room Operators In Automated Industrial Plants, Roger C. Jensen Jan 1999

Alertness-Supporting Activities For Control Room Operators In Automated Industrial Plants, Roger C. Jensen

Safety Health & Industrial Hygiene

A survey of control room operators in a nuclear power plant identified practical activities for maintaining alertness during the early morning hours. Nine on-duty operators rated 16 activities they were allowed to do on shift. Activities most effective for alertness were splashing cool water on the face, drinking coffee, and doing things that used muscles. The least effective activities were passive monitoring and studying for exams. The large range of ratings indicates that activity has a major role in operator alertness during the early morning hours.
