The footage shown here is from a home where the living conditions necessitated multiple agency interventions. This footage is just one of at least 20 homes I have encountered recently.
The device you are seeing is a Forensics ammonia detector that is calibrated and certified every year.
My team and I often encounter unsafe levels of ammonia in the air when entering homes. More often than not, we are exposed to ammonia concentrations that exceed safe habitation standards. Below, I have included some information to help you understand ammonia levels:
Ammonia has a strong, pungent odor that can be detected at concentrations as low as 5 parts per million (ppm). Most people are familiar with that unmistakable smell, especially if they have a neighbor with many cats. Even outdoor levels can reach 15 to 20 ppm, so just imagine the impact when this odor is contained in a home with minimal ventilation.
The National Institute for Occupational Safety and Health (NIOSH) has established standards for occupational exposure limits that can also be applied to home environments.
TWA (Time-Weighted Average) The maximum allowable airborne concentration over a 10-hour shift is 25 ppm (parts per million). With PPE
STEL (Short-Term Exposure Limit) The maximum concentration permitted for a 15-minute exposure, which must not be exceeded at any time, is set at 35 ppm. With PPE
As ammonia concentration increases through the thresholds of 25 ppm, 50 ppm, and 300 ppm, the required respiratory protection escalates as follows: from a half-face Air-Purifying Respirator (APR) to a full-face APR, and finally to a Self-Contained Breathing Apparatus (SCBA)..
Ammonia is a strong irritant that can cause corrosion to the eyes, skin, and upper respiratory tract. The olfactory nerves can become damaged, leading individuals to become acclimated to such smells due to the overload on their senses. This exposure can harm the respiratory tract, and depending on the level of exposure, it is possible that recovery may never occur.
Dogs have a highly specialized sensory system for tracking, survival, and environmental awareness. They possess between 100 to 300 million olfactory receptors, compared to just 5 to 6 million in humans, and they dedicate 40 times more brain tissue to processing scents. Dogs can detect microscopic chemical shifts, hormones, and volatile organic compounds linked to illness or emotions.
Given this, if we can smell ammonia, we can only imagine the effects it has on these poor animals who are subjected to it day in and day out.
Unfortunately we see this entirely too much in this field .
