SAFETY AND HEALTH ISSUES 37 Jennifer A. Heth 37.1 INTRODUCTION On a weekly basis, there are conflicting media reports indicating that something is good or bad for us, depending on the study done, the topic and the amount of press given to it. However, by reviewing the information and adding common sense and moderation to our lifestyles, we are able to discern good from bad, thus allowing us to lead healthy and safe lives. Working with composite materials, or any chemicals for that matter, should be viewed in the same manner. Know what material is used, how it is handled, what is known about it and how to reduce the risk of injury from any haz- ard associated with it. From a safety perspective, proven engineer- ing and administrative techniques and controls exist that can make the workplace safe if implemented correctly. There are fairly universal industrial hygiene protocols that merely need to be implemented to effectively minimize potential exposure to any hazard, whether it be chemical or physical. health issues, there are numerous toxi- cological papers published on chemicals used in the composites industry. However, without a toxicological background or proper analysis and interpretation of the data, it is difficult to know what the studies’ conclusions are and, more importantly, if they are valid. To assist users in understanding safety and health issues for composite materials, the Handbook of Composites. Edited by S.T. Peters. Published in 1998 Chapman & Hall, London. ISBN 0 412 54020 7 Safety and Health Subcommittee of the Suppliers of Advanced Composite Materials Association (SACMA) researched and pub- lished Safe Handling of Composite Materials (3rd Edn, April 1996). This chapter is an edited ver- sion of the booklet, with new information added as appropriate. The information is not meant to be inclusive. Rather, the reader should be aware of the issues addressed and make further investigation as needed. Note that data cited was current in 1997. 37.2 HEALTH INFORMATION TERMINOLOGY It is important to understand the terminology in order to read and assess toxicological data. This section will concentrate on some of the basic terms and definitions that are applicable to the composite user, especially in reading Material Safety Data Sheets, the most common source of information on materials. 37.2.1 TOXIC, HAZARD AND RISK These three words are used frequently and sometimes interchangeably. To avoid confu- sion, they are defined as follows. Toxic refers to a poison or poisonous sub- stance that may cause a harmful effect in the body. A substance’s toxicity characteristic is a property of the chemical, similar to its color or odor. This is as true for chemicals like water, salt or sugar as it is for cyanide, snake venom or botulism toxin (Fig. 37.1).
