Hazard signalization

Standard for gauging flammability. The most common systems for designating flammability are the Department of Transportation (DOT) definitions, the National Fire Protection Association s (NFPA) system, and the Environmental Protection Agency s (EPA) Resource Conservation and Recovery Act s (RCRA) definition of ignitable wastes, all of which use flashpoint in their schemes. The NFPA diamond, which comprises the backbone of the NFPA Hazard Signal System, uses a four-quadrant diamond to display the...

Human Hazard Signal Word (162.10(hXl)(i))—The signal word DANGER has been designated by EPA as the word which must appear on the labels of all pesticide products which meet the criteria of Toxicity Category I. Furthermore, if a product meets those criteria due to its oral, dermal, or inhalation... 

Human Hazard—For hazards to humans and domestic animals, the required precautionary statement serves as an expansion of the front panel signal word. Precautionary statements must indicate the nature of the hazard involved, the route or routes of exposure, and the precautions that should be taken to avoid accident, injury, or damage (162.10(h)(2)(i)). The appropriate hazard signal word must immediately precede the precautionary statement paragraph. See Table 10.3 for examples of precautionary statements by toxicity category as they appear in EPA s current regulations. 

If a pesticide use is classified as restricted, the statement Restricted Use Pesticide must appear on the front panel of the label, set in type of the same minimum size as that required for the human hazard signal words, see Table...

The process, as described above, has been applied to three large systems, and a number of systems for chemical plant control. In all cases, the safety barrier approach allowed searches to be limited to just a few tens of hazardous signal paths - evidence of good safety design. 

Task accomplishment and hazard control occur simultaneously in cases of this type, hazard control is perception-oriented the person is prepared to react quickly and correctly when hazard signals appear. Because control actions have been stereotyped, the person hardly has to consider how to react. 

In the other case a decision must be made after hazard indicators have been perceived. The actual process of task accomplishment must be interrupted or postponed so that actions appropriate to hazard avoidance can be taken. Perceived hazard signals must often be further analyzed and interpreted. 

Imparting the knowledge that hazard signals exist and the ability to interpret them correctly or, if necessary, to search for or create them, should be among the goals of instructional measures. It can, e.g., be necessary fora welder to recognize whether there has been a backstroke of hot gas into the bottle. In this case there could, e.g., be three potential hazard signals ...
