The following procedures will help create a risk management plan for the safe handling of pesticide-contaminated objects.Contamination includes all current pesticide treatments,legacy hazards from historic treatments and toxic elements inherent to the collection.

HAZARD IDENTIFICATION by Collection Type

Determining whether pesticide residues are present on objects canbe difficult since the residues are often not visible to the naked eye.

  • Chemical or analytical tests are required to confirm the presence of pesticides
  • Learn to recognize the types of collections that are commonly treated and the types of pesticides that are used on those collections
  • Keep in mind that organic ethnographic, taxidermied and botanical collections were regularly treated with pesticides such as arsenic,mercury and DDT

Pesticide Testing

EXPOSURE ASSESSMENT

If pesticides have been identified,conduct an assessment to define the severity of the contamination and the risks associated with handling,storing or displaying contaminated objects.

  • Determine if the contamination can be contained or eliminated
  • Consult an Industrial Hygienist or Safety Professional
  • Identify exposure risks through personal monitoring while performing work tasks
  • Use exposure study results to decide feasible ways to remediate or control exposures

REMEDIATION& DECONTAMINATION

In many cases,objects cannot be completely decontaminated and should be isolated to prevent contamination of cabinets, work spaces and exhibitions cases.

  • Clean objects using a HEPA-vacuum for dust suppression or wash to remove contaminants
  • Use a fume hood or trunk whenever possible
  • Consult federal, state and local regulations for proper disposal of each type of pesticide on objects and materials—they may be EPA regulated hazardous waste
  • Process specimens quickly to remove treatment hazards and cover during transport

  • Gaylord Archival boards, films and foams, storage boxes and trays
  • Grainger Lab supplies, personal protective equipment, plastic sheeting, testing supplies and spill kits
  • Talas Conservation supplies including personal protective equipment and HEPA vacuums

Hazardous Waste Disposal

SAFETY PROTOCOLS & TRAINING

Anyone who will be in contact with contaminated objects or areas must receive periodic training for handling,treatment and cleaning.

  • Always wear and have in stock the appropriate Personal Protective Equipment (PPE) such as gloves, respirators,lab coats,Tyvek suits and goggles that are approved for the identified contaminant
  • Create a written plan describing safety protocols once a contaminated object has been identified

HAZARD DISCLOSURE

Learning to effectively communicate about hazards is an important step in safety in the workplace.

  • Post warning signs for staff and visitors, alerting them to thehazard and required access procedures
  • Learn legal and ethical practices for the disclosure ofpesticide-contaminated items that are going to be shipped,loaned or repatriated
  • Get hazard identification from all lenders of collections,including your own staff
