Rev 12/2011
Purpose
Hampshire College has developed a policy to protect employees and the community from the hazards of lead-based paint. For all buildings built before 1978, Hampshire College will assume that lead paint is present, unless an inspection report proves otherwise. The main objective of this policy is to ensure that employees are aware of the hazards and use work practices that comply with the OSHA Lead in Construction Standard, 29 CFR 1926.62 or, when applicable, the EPA/MA Renovation, Repair, and Painting (RRP) rule when performing tasks that have the potential to disturb lead-based paint. Outside contractors are responsible for complying with these regulations when applicable, as well as MA DPH Lead Poisoning Prevention and Control (105 CMR 460.000) and MA DOS Deleading regulations (454 CMR 22.00) when performing lead abatement.
Background
Lead is a heavy, soft metal that was added to paint to make it last longer, resist moisture, speed drying, and adhere to surfaces better. According to the Occupational Safety and Health Administration (OSHA), “lead means metallic lead, all inorganic lead compounds, and organic lead soaps. Excluded from this definition are all other organic lead compounds.” Lead paint is toxic and was banned for residential use in 1978. The most common routes of exposure to lead are inhalation and ingestion. The adverse health effects of lead include damage to the circulatory system, kidneys, nervous system, bone tissue, and growth problems, and can lead to death.
Commitment
Hampshire College is committed to ensuring the safety of employees and protecting employees and the community from the hazards of lead paint. Hampshire College employees are expected and required to follow the safe work practices outlined in this policy, including donning the proper PPE, when required.
Facilities and Grounds Trades Involved
Work Area Assessment
All work areas where there is the potential for lead paint or other lead containing materials based on the age of the area and building materials will be presumed to be positive or tested to determine if lead is present. For large projects, a lead survey or inspection will be done by a certified environmental firm as part of the overall hazardous materials survey done prior to contruction activities. For small projects, trained College employees can test surfaces to be disturbed with EPA-approved lead test kits.
Exposure Level
OSHA has established a permissible exposure limit (PEL) of 50 µg/m3 (50 micrograms of lead per cubic meter of air) averaged over an eight-hour period. The established action level is 30 µg/m3, and is the level at which compliance with the OSHA 29 CFR 1926.62 Lead in Construction Standard is required. The following table indicates the anticipated exposure levels of some common construction activities. Trained Hampshire College employees are only authorized to perform tasks listed in the left column of the table. Hampshire College employees are not authorized to perform tasks for which lead exposure is presumed to be greater than 500 µg/m3 because this level of exposure would exceed the protection factor of a half-face negative pressure air-purifying respirator. Controls will be implemented to ensure that employees are not exposed to lead at this level. Wet methods must be used for all demolition, scraping, and sanding operations involving lead paint.

Exposure Assessment
To confirm that employees will not be exposed to the 8-hour time weighted average action level of 30 µg/m3, personal air monitoring will be conducted for operations lasting more than two hours that have the potential to disturb lead paint. These personal air samples will be analyzed by a certified laboratory to determine if any employee may be exposed to lead at or above the action level. Samples will be collected in such a way that they are representative of a full shift and include at least one sample for each job classification in each work area either for each shift or for the shift with the highest exposure level.
For those tasks lasting two or more hours, until we have documentation that employee exposure is not above the action level, employees are required to wear personal protective equipment (PPE). Employees must wear half or full-face respirators. OSHA requires that coveralls or similar full-body work clothing, gloves, head covering, and disposable shoe coverlets be provided in a clean and dry condition at least weekly. OSHA requires that this PPE be provided daily when employees are exposed to lead at levels over 200 µg/m3. Hampshire College will exceed OSHA’s requirement by providing this PPE daily to all employees performing tasks that disturb lead, or upon request from the employee.
Negative Initial Determination
When sampling results indicate that employees are not exposed to airborne lead concentrations at or above the action level, a written record will be made. This record will include the date of the determination; location within the worksite; the name and employee identification number of each employee monitored; any information, observations, or calculations that would indicate employee exposure to lead; any previous measurements of airborne lead; and any employee symptoms that may be attributable to exposure to lead.
Monitoring results will be provided to employees no later than five working days after receipt, either by posting in a location that is accessible to the affected employees or by giving each individual a copy. As long as sampling data was taken within the past twelve months, monitoring requirements of the OSHA standard are fulfilled, except as noted in this policy’s section “Additional Exposure Assessments.” This record will be written by and kept on file at the office of environmental health and safety.
Positive Initial Determination
When sampling results indicate that employee exposure is at or above the action level, but at or below the PEL, air monitoring will be conducted at least every six months. Monitoring will continue until at least two consecutive measurements, taken at least seven days apart, indicate exposure is below the action level. At that time, monitoring will be discontinued, except as noted in the section “Additional Exposure Assessments” of this policy. Results will be provided to employees no later than five working days after receipt, either by posting or giving each individual a copy.
When sampling results indicate that employee exposure is above the PEL, monitoring will be conducted at least every three months. Monitoring will continue until at least two consecutive measurements, taken at least seven days apart, indicate exposure is below the PEL, but at or above action level. At this time, monitoring will be conducted at least every six months until at least two consecutive measurements, taken at least seven days apart, indicate exposure is below the action level. At that time, monitoring will be discontinued, except as noted in the section “Additional Exposure Assessments” of this policy. Results will be provided to employees no later than five working days after receipt, either by posting or giving each individual a copy. When exposure is at or above the PEL, a statement will be included on the posting or individual’s copy notifying them that exposure was at or above the PEL and of the corrective action to be taken to reduce exposure.
Since most College operations do not normally last a duration of six months or longer, the facilities and grounds foreman and office of environmental health and safety will collaborate to determine sampling schedules to ensure that we have current data that is representative of specific work activities. These records will be kept on file at the office of environmental health and safety.
Additional Exposure Assessments
Whenever there is a change of equipment, process, control, personnel, or a new task has been initiated that may result in additional employees being exposed to lead at or above the action level or may result in employees already exposed at or above the action level being exposed above the PEL, additional monitoring will be conducted.
Residential, School, and Child Care Facility Requirements
The EPA Renovation, Repair, and Painting (RRP) rule, effective 4/22/10, requires that contractors performing renovation, repair, and painting projects that disturb lead-based paint in homes and child-occupied facilities (includes day care centers and schools occupied by children under 6) built before 1978 must be certified and must follow specific work practices to prevent lead contamination. Effective July 9, 2010 the Massachusetts Division of Occupational Safety was authorized by EPA to administer this standard, with corresponding regulatory requirements detailed in 454 CMR 22.00.
At Hampshire College, the children’s center was built after 1978 and student housing falls under an EPA exemption from the rule. Other residential properties and staff apartments are subject to the rule. For those occupancies, unless the repairs meet the definition of a minor repair, the work must be performed by Hampshire College certified lead-safe renovator-supervisors, or a licensed lead abatement or certified lead-safe renovation contractor, unless testing determines lead is not present.
The College has identified the following properties maintained by facilities and grounds for which the RRP rule would apply:
The following minor repairs or maintenance activities are not covered by the rule:
Minor repairs and maintenance activities do not include window replacement and projects involving demolition or prohibited practices (burning or torching, sanding, grinding, or other high speed operations).
Requirements for Work Performed by College Employees
Indoor Work Practices
Outdoor Work Practices (when distrurbing more than 20 SF)
Waste Management
All lead paint chips must be collected in a DOT-approved container. The container should be labeled with a hazardous waste label that should list "lead paint chips" as the waste name, "lead" as the ingredient, and "toxic" as the hazard.
In non-residential areas, lead paint debris, such as architectural building components, (i.e. doors, window frames, painted wood, etc.), dust and sludge must be analyzed by a certified laboratory using Toxicity Characteristic Leaching Procedure (TCLP). If the results from a representative sample of the waste stream exceed the regulatory limit of 5 mg/L of lead in the waste leachate then the waste must be managed and disposed of as hazardous.
Waste generated from work in residential areas should be collected in plastic bags and can be disposed of as household trash in a municipal solid waste landfill or municipal solid waste combustor, in accordance with Massachusetts DEP regulation 310 CMR 30.104 and the USEPA memorandum “Regulatory Status of Waste Generated by Contractors and Residents from Lead-Based Paint Activities Conducted in Households.”
Respirators
Respirators will be provided upon employee request, provided that the employee is, or becomes, an authorized respirator user under the Hampshire College respirator program. Respirators are required when an employee’s exposure to lead is at or exceeds the PEL or when performing tasks for which we do not have a negative exposure assessment. Hampshire College employees are not anticipated to perform tasks that will exceed the PEL; however, in the event that this becomes necessary, respirators will be required in accordance with the OSHA standard. Additionally, a written compliance program would have to be implemented, reviewed, and updated at least every six months.
Medical Questionnaire
Every employee in the respirator program will complete a medical questionnaire prior to wearing a respirator and annually thereafter. The questionnaire will be reviewed by a physician or other licensed health care professional (PLHCP). If required by the PLHCP, a medical exam will be given. Additionally, a medical exam will be provided if the employee has difficulty breathing during fit testing or while using the respirator.
Medical Surveillance
If an employee is exposed to lead at the action level of 30 µg/m3, on any one day, initial medical surveillance, consisting of biological monitoring in the form of blood sampling and analysis for lead and zinc protoporphyrin (ZPP) levels, will be made available. If an employee’s exposure to airborne lead is at the action level for more than 30 days in any consecutive 12 months, then a medical surveillance program will be implemented according to the following schedule:
Additionally, for employees in the medical surveillance program, a medical exam and consulation will be made immediately available if the employee:
Training
All employees who perform tasks that have potential to disturb lead must initally complete th Hampshire College Lead Paint Safety Training that covers the OSHA Lead in Construction Standard. This training must be repeated annually for any employees subject to lead exposure at/above the action level on any day. Employees performing work, other than minor repairs, in pre-1978 homes or child-occupied facilities must complete the initial 8-hour MA/EPA Lead-Safe Renovator-Supervisor course and attend a 4-hour refresher course every 5 years.
Records
Records of lead paint abatements, lead-safe renovations, inspections, testing and sampling, letters of compliance, employee training records, and air monitoring data will be kept by the director of environmental health and safety.
Program Review
This program will be reviewed periodically by facilities and grounds and the office of environmental health and safety to ensure compliance with OSHA, EPA, MA and any other applicable regulations. Additionally, projects performed throughout the year can create the opportunity to evaluate our work practices to determine if procedures outlined in this policy are adhered to and if there is new information or guidelines that can be implemented to improve this policy and our overall environmental and safety efforts.
