Police evidence rooms in need of good IAQ

Collecting and storing evidence is an important
part of police work and legal proceedings.

Collecting and handling evidence is often one of the weirdest parts of a police officer's work, but it is very important to properly store evidence for investigations and legal proceedings.

In most police evidence rooms, there is more than one custodian responsible for the evidence. The job is very technical, as any evidence that is lost or tempered with can't be used in a case in court.

To make sure they can tell where the evidence is, who's had access to it and when, the technicians need to put in place a rigorous process and go through regular internal audits. Digital record keeping helps with making evidence easier to track, and security is paramount.

The evidence room houses evidence such as illicit and prescription drugs, weapons as well as items connected to crimes, many of which will be returned to their owners, auctioned off or destroyed once the case has been closed.

Metal shelves and neatly labelled boxes make for an organized room, but the evidence technicians have to be careful about the indoor air quality in the evidence room.

Without proper ventilation and air exchanges, evidence room personnel may be exposed to airborne fumes, mold (especially Aspergillus mold from improperly stored marijuana), particles, dust, chemicals and other contaminants.

Measures for a healthy evidence room

Breathing contaminated air can affect a police officer's health and well being. Continuous exposure to poor indoor air quality has been associated with less productivity, respiratory disease and many other illnesses.

There are many measures that can be taken to make the evidence room (and other areas of the department) a safer and healthier place:

• Use a diligent process for storing evidence
• Use personal protective systems (such as masks and gloves) when moving and handling stored evidence
• Monitor and adjust indoor heating, ventilation and air conditioning system
• Use a portable air purifier with activated carbon, HEPA and UV germicidal filtration to remove chemicals, gases, fumes, odors, particles, dust and biological contaminants
• Keep the evidence room clean and organized

Avoiding chemical and mold exposures in drug evidence rooms - Part II

Tips for officers in evidence rooms
to minimize exposures to toxins.

Storing drugs in evidence rooms and drug vaults at law enforcement agencies poses a significant health risks for the employees in charge of retrieval, maintenance and disposal.

They could be exposed to drug particles, chemical fumes, volatile organic compounds, mold spores, mold mycotoxins (terpenes) and many other contaminants.

While exposure levels may be low, inhaling these types of indoor air pollutants over an extended period of time may become a health risk.

There have been complaints from police officers ranging from respiratory problems to fatigue and anxiety, among many others (see Part I).

Based on case studies and health hazard evaluations, the National Institute for Occupational Safety and Health (NIOSH) has put together some general recommendations for drug evidence rooms:

1. Keep drug quantities under control. Frequent disposal of drugs can reduce the chances of exposure and off-gassing materials.
2. Make sure marijuana and other plant-based drugs are dried properly and set up a drying chamber inside the evidence room, if needed.
3. Use chemical and particle filters (activated carbon and HEPA) in the evidence room and ensure that filters are replaced regularly.
4. Have the HVAC (especially the ventilation) system inspected by a ventilation engineer and make improvements, if necessary.
5. Store dried marijuana in sealed plastic bags. If they need to be stored in ventilated cardboard boxes, they should be in an enclosed area in the evidence room with exhaust ventilation to contain odors.
6. Seal synthetic drugs in plastic.
7. Keep a relative humidity level of 30-50% to minimize mold growth.
8. Keep the evidence room clean and well maintained, using environmentally friendly and non-toxic cleaners, gloves and vacuum cleaners with HEPA filters.
9. Improve organization and avoid clutter.
10. Use a cart to transport evidence.
11. Avoid skin contact with marijuana as well as other drugs and evidence materials to reduce the potential for irritation and allergic reactions.
12. Alert employees of possible risks and open channels of communication to address problems quickly and efficiently.
13. Develop written policies and standard operating procedures and train employees accordingly.

• Mold wreaks havoc on materials stored in evidence rooms

Chemical and mold exposure an occupational risk in law enforcement – Part I

Improperly dried or stored marijuana can expose police
officers to mold spores and chemicals.

Working in an evidence room at any law enforcement agency can be an occupational health risk, industrial hygienists warn.

For crimes that involve drugs, police officers need to store evidence in a drug vault, and in most cases, indoor air quality suffers.

Synthetic drugs such as methamphetamine can emit dangerous chemical fumes, while plant-based drugs such as marijuana are susceptible to mold growth and often expose officers to Aspergillus mold spores. Marijuana also produces volatile organic compounds called terpenes that contribute to the drug’s taste and smell.

Employees may have to spend several hours each day in the evidence room, receiving, storing and retrieving evidence, transporting drugs and other materials, maintaining inventory, and getting evidence ready for disposal. These activities can expose them to drug particles, mold spores, volatile chemicals from drugs as well as from “air freshening” products.

Occupational Safety and Health intervention may become necessary if the evidence room employees start exhibiting health symptoms related to exposure, which may include:

• Nose bleeds
• Respiratory problems
• Skin rashes
• Memory fog
• Fatigue
• Anxiety
• Vision problems
• Burning eyes
• Facial twitches

Some employees show higher sensitivities to chemicals and molds than other employees, and while some people may experience symptoms right away, it may take years for others to develop any health effects.

The risks of exposures to certain drugs such as methamphetamine and cocaine at high levels is well known, but low level exposures over extended periods of time have not been researched, occupational hygienists say.

However, there is limited evidence linking low levels of indirect drug exposures to acute or chronic health effects, there are reports in the scientific literature of people experiencing skin rash from occupational exposure and handling of marijuana plants and materials, with symptoms increasing over time with ongoing exposure (Majmudar et al., 2006; Williams et al., 2008).

Exposure to chemical fumes from evidence leaves police officers ill

Improper storage and escaping fumes put
officers in evidence rooms at risk.

The risks for those working in law enforcement don’t stop at the street level – they can lurk in evidence rooms and exhibit centers where old drugs, chemicals and other materials are stored.

The story of two Australian police officers who got sick after being exposed to toxic fumes is an extreme example of what can happen when inadequate health and safety measures are in place.

The two policemen were asked in March 2009 to perform a drug audit in the Sydney Police Centre’s drug exhibit center.

The room was about 4 x 5 meters big, not ventilated and was crammed with drugs and other chemicals up to 15 years old.

The officers walked in without wearing protective equipment and were hit with the toxic fumes instantly.

Three years later, they are unable to work and allege they were not given any training, special equipment or instructions.

The officers claim they were exposed to old methamphetamine in a particularly toxic exposure incident. Not only did they develop severe headaches, coughing, burning sensation in nose and throat and other symptoms during the drug audit, but their health continued to deteriorate over time, they say.

They are suing the police force for dozens of negligent acts and more than 50 breaches of the duty of care.

Meth lab cleanups “on hold” as money dries up

Police need to find a way to
pay for methlab cleanups.

Law enforcement officials at the forefront of the war on meth in the United States had to make a sudden retreat after they ran out of funds to pay for the cleanups of the toxic waste that is generated by labs.

An AP article details the problems caused for police and sheriff’s departments across the nation by cutbacks from the federal government that helped law enforcement agencies to dispose of seized labs.

The government’s decision to cancel the program took away millions of dollars that were slated for the fight against meth labs.

Cutbacks affect investigative work

Law enforcement agencies often had to cancel special initiatives or assignments such as undercover work, door-to-door investigations and stakeouts to locate operating meth labs.

The AP analysis shows that the number of seized labs has dropped drastically in major meth-producing states.

Without the federal money, states have to find a way to replace the funds or make the cleanups less expensive.

Typical cleanups cost $2,500 to $5,000 per lab.

The problem is, meth labs are thriving in the US, with the number of new meth users rising each year and a growing number of shipments coming from Mexico.

What is meth?

Methamphetamine is a psychostimulant of the phenethylamine and amphetamine class of psychoactive drugs. It has high potential for abuse and addiction and in addition to psychological harm, physical harm such as cardiovascular damage, may occur with chronic use or acute overdose.

Short-term exposure to high concentrations of chemical vapors that may exist in methamphetamine laboratories can cause severe health problems or even result in death. Exposure to these substances can occur from volatile air emissions, spills, fires, and explosions.

Because meth is made using a volatile mix of ingredients such as battery acid, drain cleaner and ammonia, only cleanup crews with specialized training are allowed to handle the materials found in labs.

The waste and debris cannot be dumped in a regular landfill, only in specially approved waste sites.

Cleanup programs need to be adapted

The only solution seems to be for the states to implement their own cleanup programs.

In states where such programs already exists, local police and deputies are trained to remove meth waste and collect it in designated containers - essentially small metal storage buildings. The DEA picks up the waste and disposes of it.

The system is far less expensive - $500 for a typical cleanup.

Now some states that previously used the COPS money are developing their own container systems, including Michigan and Tennessee, which began its program last month. Arkansas also is looking at a container program.

Health and safety issues: Mold in the workplace

Water is a beautiful thing - unless it leaks
into buildings and causes IAQ problems.

Water damage in the workplace can be a result of a variety of reasons, among them a leaking roof, broken pipes, heavy rains or similar problems.

But excessive moisture can turn into a serious problem in a matter of 48 hours, when mold starts to grow, which can affect the health and well-being of building occupants.

When heavy rains caused water damage at the Douglas County Sheriff’s Office recently, management did the right thing and evacuated many employees.

According to an article in the Alexandria Echo Press, the water damage along with hot and humid weather prompted concerns about mold growth. Water was running down walls and saturated the building, and it was not clear where the leak occurred.

According to renovation experts, it’s often difficult to pinpoint the source of the leak, since water can travel behind walls and along supporting structures before it can be seen.

The precautionary measure to evacuate the officers is a smart move – exposure to mold spores and mold mycotoxins can cause or aggravate existing health conditions in many individuals and cause symptoms such as

• Headache
• Sneezing
• Shortness of breath
• Nausea
• Fatigue
• Dizziness
• Coughing
• Irritation of eyes, skin, nose and throat

Mold often grows on marijuana stored
in evidence rooms.

Mold can also become a major problem in property and evidence protection rooms where marijuana and other hazardous materials are stored. Aspergillus mold is a common occurrence on improperly dried or improperly stored marijuana.

Electrocorp offers efficient, versatile and cost-effective stand-alone air filtration systems for Law Enforcement and other industrial or commercial applications.

The air cleaners remove a wide range of contaminants such as chemicals, particles, odors, bacteria, viruses and mold by leveraging a multi-stage filtration system:

RAP Series: Ultimate protection
for Law Enforcement agencies.

1. Carbonized pre-filters
2. 15 lb. to 120 lb. activated carbon filter (most efficient medium for the removal of airborne chemicals and odors)
3. Medical-grade or micro-HEPA (most efficient filter for the removal of small particles)
4. UV germicidal filtration (the UV lamp neutralizes live contaminants such as bacteria, viruses and mold mycotoxins

Mold wreaks havoc on material stored in evidence rooms

Law enforcement officers have a dangerous job – even when their primary responsibility is to guard the property evidence and storage rooms. One of the biggest hazards they face is mold, and more specifically, the Aspergillus fungus.

Marijuana attracts the Aspergillus fungus.

Aspergillus grows on any biological item, but it really likes marijuana and it doesn’t need much moisture to prosper and grow. When marijuana is stored in plastic, even minute amounts of moisture that is held by the plastic can support the growth of Aspergillus.

Aspergillus can affect law enforcement officers' health

The problem is that even perfectly dried marijuana plants still contain 10-15% water. When property evidence officers handle the decaying material, they can be exposed to mold spores that enter the human body through the ears and nose. Reported health effects are stuffiness, a feeling of being unwell, coughing, wheezing and lung damage.

Another issue with plastic is the destruction of evidence. When officers use plastic to hold evidence, the retained moisture can cause it to mold, corrode or rust, and plastic is often blamed for destroying latent fingerprints. Some law enforcement officers ask that plastic is only used for drug-related items, except marijuana, and jewelry.

To stave off mold infestations, evidence storage rooms need to

• Install adequate ventilation systems and make regular filter replacements
  
• Implement an improved storage system: Don’t store copious amounts of marijuana, especially after a case has been adjudicated. Document and photograph excessive amounts of marijuana, and only keep samples. The samples must be cleaned and sealed appropriately
  
• Ensure good housekeeping procedures: discard all materials that are visibly affected by fungi, clean all surfaces and disinfect the area, supply workers with protective equipment
  
• Recognize the hazards and the best ways to deal with them
  
• Look into other air cleaning methods to protect law enforcement officers. Electrocorp’s industrial air purifiers, including the RAP and RSU series are powerful air scrubbers that can help provide better air in storage rooms
  
• Consider each case individually for marijuana storage. Burlap or paper bags let the moisture escape, but they also won’t hold off mold spores. Impermeable bags made out of plastics can cause the contents to turn into a mushy soup of questionable evidential value. The best choice is dependent on the amount of time it is stored, the quality of the material and the existing situation in the evidence room.
