Document Number: [SWP-NUMBER] Revision Date: [DATE] Next Review Date: [NEXT REVIEW DATE] Department: [DEPARTMENT NAME]
1. Scope
This Safe Work Procedure (SWP) outlines the necessary safety precautions and procedures for applying coatings to tennis courts during construction. It covers surface preparation, mixing of coating materials, application methods (including spraying and manual application), and post-application cleanup. This SWP applies to all personnel involved in the coating process, including supervisors, workers, and contractors. It is applicable for both indoor and outdoor tennis court construction projects.
This SWP should be used in conjunction with the manufacturer's instructions for the specific coating materials being used, as well as any relevant site-specific safety plans and regulations.
2. Definitions
Coating Material: The liquid or powder substance applied to the tennis court surface to provide the desired playing characteristics and aesthetics.
Flashpoint: The minimum temperature at which a liquid gives off vapor within a sufficient concentration to ignite [1].
Lower Flammable Limit (LFL): The lowest concentration of a material that will propagate a flame [1].
Spraying Area: Any area in which dangerous quantities of flammable vapors or mists, or combustible residues, dusts, or deposits are present due to the operation of spraying processes [2].

## SUBSTANCE TECHNICAL GUIDELINES FOR ACRYLONITRILE Appendix D lists methods of sampling and analysis which have been tested by NIOSH and OSHA for use with acrylonitrile. NIOSH and OSHA have validated modifications of NIOSH Method S-156 (See Appendix D) under laboratory conditions for concentrations below 1 ppm. The employer has the obligation of selecting a monitoring method which meets the accuracy and precision requirements of the standard under his unique field conditions. The standard requires that methods of monitoring must be accurate, to a 95-percent confidence level, to ±35-percent for concentrations of AN at or above 2 ppm, and to ±50percent for concentrations below 2 ppm. In addition to the methods described in Appendix D, there are numerous other methods available for monitoring for AN in the workplace. Details on these other methods have been submitted by various companies to the rulemaking record, and are available at the OSHA Docket Office. - B. Since many of the duties relating to employee exposure are dependent on the results of monitoring and measuring procedures, employers shall assure that the evaluation of employee exposures is performed by a competent industrial hygienist or other technically qualified person. ## V. Protective Clothing Employees shall be provided with and required to wear appropriate protective clothing to prevent any possibility of skin contact with liquid AN. Because acrylonitrile is absorbed through the skin, it is important to prevent skin contact with liquid AN. Protective clothing shall include impermeable coveralls or similar full-body work clothing, gloves, headcoverings, as appropriate to protect areas of the body which may come in contact with liquid AN. Employers should ascertain that the protective garments are impermeable to acrylonitrile. Non-impermeable clothing and shoes should not be allowed to become contaminated with liquid AN. If permeable clothing does become contaminated, it should be promptl…
