Introduction Explain why samples are taken in process systems. Describe some hazards associated with sampling materials. Describe personal protective clothing that should be worn when taking samples of hazardous and non-hazardous materials. Describe two types of respirators that are worn when sampling involves materials that produce harmful dust particles or toxic fumes. Liquids Describe how to keep liquid samples from being contaminated when they are taken. Explain how to make sure that a representative sample of a liquid is obtained. Describe the information that Is typically included on a sample label. Solids and Gases Describe how to obtain contaminant-free representative samples of process solids. Describe how to obtain contaminant-free representative samples of process gases.
