specific contaminant(s) to which the Employee is exposed. · Respiratory protective equipment will be provided and maintained in a clean and sanitary manner using equipment manufacturer’s procedures. · Respiratory protective equipment will be properly stored and inspected before and after each use. · Employees shall not use a respirator until he/she has been thoroughly trained in its use, fit, limitations, emergency situations, maintenance, storage and medical symptoms, including having undergone and passed a quantitative or qualitative fit test. · Employees will complete a medical questionnaire and be fit tested prior to respirator use. · Respirators with tightfitting facepieces shall not be worn by Employees who have facial hairs, glasses, etc. that comes between the sealing surface of the facepiece or interferes with the valve function. · Employees must leave the area if they detect a break-through or resistance or need to wash or change cartridges. It is not expected that BL Companies’ Employees will be required to work in Immediate Danger to Life and Health (“ IDLH ”) atmospheres. If a potential IDLH atmosphere is encountered during HAZWOPER work, a health and safety specialist or industrial hygienist will be consulted to ensure all proper precautions and engineering controls are in place before work in the IDLH atmosphere begins. 7.2 Hazardous Communications Plan Purpose On March 26, 2012, OSHA’s final revised Hazard Communication Standard (“ HCS ”) was published in the Federal Register, aligning it with the Globally Harmonized System of Classification and Labeling of Chemicals (“ GHS ”). The purpose of this written Hazardous Communications Plan is to ensure that the Company’s Employees are informed, by means of labels, Safety Data Sheets (“ SDS ”) and training, of the physical and health hazards to which they may be exposed. This written program meets the requirements of OSHA’s Hazard Communication Standard for the Construction Industry, 29 CFR 1926.59.

7.1 Respiratory Protection Program

Purpose This program establishes uniform guidelines for complying with the requirements of OSHA’s Respiratory Protection Standard, 29 CFR 1910.134 for the proper selection, use and care of respiratory protection equipment. Scope This Section applies to those Employees who are required to use respiratory protective devices due to exposure to respiratory hazards (e.g. harmful dusts, fogs, fumes, mists, gases, smokes, sprays or vapors). Policy Every consideration will be given to the use of effective engineering controls to eliminate or reduce exposure to respiratory hazards to the point where respirators are not required; however, when feasible engineering controls are not effective in controlling respiratory hazards, appropriate respiratory protective equipment and necessary medical examinations will be provided by BL Companies at no charge to the Employee. Medical examinations will be confidential, held during normal working hours and convenient to the employee. Employees will be given an opportunity to discuss the results of the examination with a licensed health care professional. General Respirator Protection On projects where there is a risk of exposure to respiratory hazards, there should be a site specific HASP written and a respiratory protection program shall be utilized and must be administered by a suitably trained program administrator. The elements of such a program shall be appropriate to the specific risks present. · When effective engineering controls are not feasible, or while they are being instituted, appropriate respirators shall be used pursuant to 29 CFR 1910.134. · Respiratory protective devices shall be approved by the U.S. Bureau of Mines/National Institute for Occupational Safety and Health or OSHA for the

Scope This Section applies to all BL Companies’ Employees.
