2 Detergent Suicide Detergent Suicide Presented by City of Raleigh Fire Department Hazmat Team

3 What is Detergent Suicide? Name comes from the type of ingredients used Name comes from the type of ingredients used Mixture of toilet bowl cleaner and an organic phosphate – insecticide, fungicide Mixture of toilet bowl cleaner and an organic phosphate – insecticide, fungicide Sometimes Muriatic or Sulfuric Acid is substituted for cleaner Sometimes Muriatic or Sulfuric Acid is substituted for cleaner Originated in Japan – slowly proliferating all over the world Originated in Japan – slowly proliferating all over the world

4 What happens? Mixing the aforementioned chemicals together produces a deadly gas: Mixing the aforementioned chemicals together produces a deadly gas: Hydrogen Sulfide

5 What is Hydrogen Sulfide? Toxic, colorless gas Toxic, colorless gas Smells like rotten eggs Smells like rotten eggs Extremely flammable Extremely flammable

6 Properties IDLH:100 ppm Flammable Range: 4% to 46% Ignition temp approx. 500 0 F Vapor Density:1.2 (Heavier than air) Vapor Pressure @ 68 0 F is 17.6 atm It will dissipate quickly outside It will dissipate quickly outside

7 Toxic Levels of Concern Odor Threshold:.001 to 0.13 ppm Odor Threshold:.001 to 0.13 ppm Olfactory Fatigue begins at about 20 ppm Olfactory Fatigue begins at about 20 ppm Ten minute AEGL-2:41 ppm Ten minute AEGL-2:41 ppm Irreversible, serious, long-lasting effects or impaired ability to escape. Irreversible, serious, long-lasting effects or impaired ability to escape.

8 Signs and Symptoms Target Organs: Eyes, Respiratory Tract, Central Nervous System Target Organs: Eyes, Respiratory Tract, Central Nervous System Symptoms: Symptoms: Eye, mucous membrane and skin irritation Eye, mucous membrane and skin irritation Memory loss, confusion, headache, dizziness Memory loss, confusion, headache, dizziness Shortness of breath, cough, tightness in the chest, pulmonary edema Shortness of breath, cough, tightness in the chest, pulmonary edema Difficulty breathing/swallowing, abdominal pain, nausea, vomiting, diarrhea Difficulty breathing/swallowing, abdominal pain, nausea, vomiting, diarrhea Tremors, convulsions, coma Tremors, convulsions, coma

9 Basic Life Support Remove victim from exposure Remove victim from exposure Decontaminate Decontaminate Brush solids from clothing (if any) Brush solids from clothing (if any) Remove clothing – contain for disposal. Remove clothing – contain for disposal. Flush victim with copious amounts of water using mild detergent – minimum 15 minutes Flush victim with copious amounts of water using mild detergent – minimum 15 minutes Flush eyes with lukewarm water – minimum 15 minutes Flush eyes with lukewarm water – minimum 15 minutes

10 Basic Life Support, contd… Administer Oxygen, 10-12 LPM via NRB Administer Oxygen, 10-12 LPM via NRB Transport immediately to Hospital Transport immediately to Hospital Advanced Life Support… Advanced Life Support… Refer to local protocol Refer to local protocol

11 Basic Life Support, contd… NOTE: Performing these BLS and decontamination functions should be performed wearing appropriate PPE NOTE: Performing these BLS and decontamination functions should be performed wearing appropriate PPE This includes; This includes; Level C PPE – Chemical splash suit, nitrile gloves, chemical boots, appropriate respirator Level C PPE – Chemical splash suit, nitrile gloves, chemical boots, appropriate respirator Use SCBA if victims area concentrations were greater than 100 ppm Use SCBA if victims area concentrations were greater than 100 ppm

12 Scene size-up Some scenes will be obvious… Some scenes will be obvious… Well marked with warnings Well marked with warnings Obvious chemicals in the vehicle/structure Obvious chemicals in the vehicle/structure

13 Scene size-up contd… Others may not… Others may not…

14 Things to consider Overall scene safety Overall scene safety Does the scene appear to be unusual in any way? Signage, odors, victims? Does the scene appear to be unusual in any way? Signage, odors, victims? Inside or outside? The gas - if present – will persist much longer in an enclosed space Inside or outside? The gas - if present – will persist much longer in an enclosed space Any indicators that chemicals are present? Any indicators that chemicals are present? Victim slumped over steering wheel? Victim slumped over steering wheel? Bystanders showing signs and symptoms of H 2 S? Bystanders showing signs and symptoms of H 2 S?

15 Things to consider, contd… A yes to any one of the previous items would be cause for concern A yes to any one of the previous items would be cause for concern Call Hazmat Call Hazmat DO NOT make entry into the vehicle or building/room. DO NOT make entry into the vehicle or building/room. Keep all ignition sources away from area Keep all ignition sources away from area

16 Things to consider, contd… Monitoring for H 2 S with a monitor calibrated with a gas other than H 2 S will require the use of a correction factor Monitoring for H 2 S with a monitor calibrated with a gas other than H 2 S will require the use of a correction factor Rae Systems correction factors for their MultiRae PIDs are as follows (if calibrated with 100ppm isobutylene): Rae Systems correction factors for their MultiRae PIDs are as follows (if calibrated with 100ppm isobutylene): For 10.6 eV – 3.3 For 10.6 eV – 3.3 For 11.7 eV – 1.5 For 11.7 eV – 1.5

17 Items for the future We have been lucky so far – incidents have been outside and marked with warning signs We have been lucky so far – incidents have been outside and marked with warning signs In Japan, this occurs in apartment buildings – many others become involved In Japan, this occurs in apartment buildings – many others become involved Meth labs could be booby-trapped with this type of device Meth labs could be booby-trapped with this type of device Hostage situations may involve this – firing a flash-bang grenade into this type of environment would be very explosive Hostage situations may involve this – firing a flash-bang grenade into this type of environment would be very explosive

18 Recent Occurrences Yet another detergent suicide forced residents of an apartment building to evacuate on June 4, 2008. 34 residents were evacuated and one woman was taken to the hospital. The suicide victim was in his late 20s.
