1.1 Scope. 1.1.1* This standard shall specify minimum requirements for the design, performance, testing, documentation, and certification for liquid splash–protective ensembles, ensemble elements, and protective clothing used by emergency response personnel during hazardous materials incidents. A.1.1.1 The requirements of this standard were developed taking into consideration the needs of emergency response personnel for hazardous materials emergencies. This application can entail a variety of chemical, physical, and other hazards. Other protection needs should warrant a thorough review of the requirements in this standard, such as routine industrial operations to determine their applicability. There are no requirements in this standard that address reuse or multiple wearings of liquid splash–protective ensembles. Users are cautioned that exposure of liquid splash–protective ensembles to chemicals could require disposal, particularly if the effectiveness of decontamination cannot be assessed. At the time this standard was prepared, the characteristics of a dust or particulate flash fire have not been defined by the Technical Committee on Hazardous Materials Protective Clothing and Equipment and, therefore, the Committee has chosen not to assume that these exposures are similar to a chemical flash fire nor are the optional additional requirements for chemical flash fire protection adequate as minimum requirements for dust or particulate flash fire protection. 1.1.2 This standard shall also specify additional optional criteria for liquid splash–protective ensembles for escape protection only from chemical flash fires encountered during hazardous materials incidents. 1.1.3 This standard shall specify requirements for new liquid splash–protective ensembles, new ensemble elements, and new protective clothing. 1.1.4* This standard alone shall not specify requirements for protective ensembles or clothing for hazardous materials emergencies involving known or suspected human carcinogens, or hazardous materials with known skin toxicity that are present as vapors, or hazardous material vapor atmospheres. A.1.1.4 Organizations responsible for specialized hazardous materials response functions including ionizing radiation, biological, liquefied gas, or cryogenic liquid hazards, explosive atmospheres, or fire-fighting applications should use protective clothing and equipment specifically designed for protection for those operations. 1.1.5* This standard alone shall not specify requirements for protection from chemical or biological terrorism agents or from chemical or biological terrorism incidents. Requirements for such protection shall be provided by protective ensembles that are certified as compliant with NFPA 1994, Standard on Protective Ensembles for First Responders to CBRN Terrorism Incidents, or ensembles that are certified as compliant with NFPA 1991, Standard on Vapor-Protective Ensembles for Hazardous Materials Emergencies. A.1.1.5 See A.1.1.4. 1.1.6* This standard alone shall not specify requirements for protective clothing for any fire-fighting applications. A.1.1.6 See A.1.1.4. 1.1.7* This standard alone shall not specify requirements for protection from ionizing radiation; biological, liquefied gas, or cryogenic liquid hazards; or from explosive atmospheres. A.1.1.7 See A.1.1.4. 1.1.8 This standard shall not specify requirements for the respiratory protection that is necessary for proper protection with the protective ensemble. 1.1.9 This standard shall not specify requirements for any accessories that could be attached to the product but are not necessary for the product to meet the requirements of this standard. 1.1.10 Certification of compliant liquid splash–protective ensembles, ensemble elements, and protective clothing to the requirements of this standard shall not preclude certification to additional appropriate standards where the ensemble, ensemble elements, or protective clothing meet all the applicable requirements of each standard. 1.1.11 This standard shall not be construed as addressing all of the safety concerns, if any, associated with its use for the designing, manufacturing, testing, or certifying of product to meet the requirements of this standard. It shall be the responsibility of the persons and organizations that use this standard to establish safety and health practices and determine the applicability of regulatory limitations prior to use of this standard. 1.1.12 Nothing herein shall restrict any jurisdiction or manufacturer from exceeding these minimum requirements.
