|OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at http://www.osha.gov.|
Steam and hot-water pipes. All exposed steam and hot-water pipes within 7 feet of the floor or working platform or within 15 inches measured horizontally from stairways, ramps, or fixed ladders shall be covered with an insulating material, or guarded in such manner as to prevent contact.1910.262(c)(9):
Steam pipes. All pipes carrying steam or hot water for process or servicing machinery, when exposed to contact and located within seven feet of the floor or working platform shall be covered with a heat-insulating material, or otherwise properly guarded.1910.23(c)(3):
Regardless of height, open-sided floors, walkways, platforms, or runaways above or adjacent to dangerous equipment, pickling or galvanizing tanks, de-greasing units, and similar hazards shall be guarded with a standard railing and toe board.1910.147: The control of hazardous energy (lockout/tagout) standard covers hazardous energy, including thermal, during the servicing and maintenance of machines or equipment. Thermal energy may be dissipated or controlled, and it is the result of mechanical work, radiation, or electrical resistance. This standard addresses practices and procedures that are necessary to disable machinery or equipment and to prevent the release of potentially hazardous energy while maintenance and servicing activities are performed.
Protective equipment, including personal protective equipment for eyes, face, head, and extremities, protective clothing, respiratory devices, and protective shields and barriers, shall be provided, used, and maintained in a sanitary and reliable condition wherever it is necessary by reason of hazards of processes or environment, chemical hazards, radiological hazards, or mechanical irritants encountered in a manner capable of causing injury or impairment in the function of any part of the body through absorption, inhalation or physical contact.The personal protective equipment standard would apply to hot surfaces where the hazards have not been eliminated through engineering or administrative controls. This standard requires employers to assess the workplace to determine if hazards that require the use of PPE are present or are likely to be present. The employer must select and have affected employees use properly fitted PPE suitable for protection against these hazards, as well as provide employee training and conduct periodic inspections to assure procedures are being followed. Suitable thermal protection would be necessary to provide employees with thermal insulation from hazardous hot pipe surfaces.
Each employer shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees.The private sector has specifically addressed the issue of exposed heated surfaces. The national consensus standard, "Standard Guide for Heated System Conditions that Produce Contact Burn Injuries (C 1055-92)," issued by the American Society for Testing Materials (ASTM)1 addresses this issue. The standard establishes a means by which the engineer, designer, or operator can determine the acceptable surface temperature of an existing system where skin contact may be made with a heated surface. Personal injury resulting from contact with heated surfaces can be prevented by proper design of insulation systems or the usage of other protective measures. A copy of that standard has been enclosed for your information.
