What are the four ways hazardous materials can enter the body?
- Inhalation
- Absorption
- Injection
- Ingestion
These routes highlight the various methods through which hazardous materials can affect human health.
Who determines the level of PPE for Hazmat?
- Hazardous Materials Assistant Safety Officer
- Technical Reference
- Hazardous Materials Group Supervisor
These individuals work together to assess the situation and determine appropriate personal protective equipment.
What is a Level A Hazmat Suit used for?
Used when possibility of skin absorption and possibility of vapors.
Fully encapsulating suit even covering SCBA.
What does a Level B Suit provide?
Splash Protection with SCBA, when there is no gaseous absorption.
SCBA is outside of the suit.
What is the purpose of a Level C Hazmat Suit?
Offers splash protection, but substance is known and hazard is minimal.
There is no SCBA, might use N95 or respirator.
What is a Level D Haz Mat suit?
Structure Gear, does not provide wearer against any chemical contact.
It is the least protective level of personal protective equipment.
What is the difference between CCCFPD Hazmat Team and County Health?
- CCCFPD HMRT: emergency response phase, mitigate the problem, stop the problem, we don’t clean it up
- County Health: assumes control of incident once in recovery phase, and do cleanup
This distinction highlights the different roles in managing hazardous material incidents.
What three con fire units make up the response to provide a required 8 member Type 1 Hazmat Team?
- HM 87: Capt HZ Sup, Engineer Entry Leader, FF Tech Ref
- Eng 15: 3 personnel usually Entry Team
- Eng 3: 2 personnel, Captain and Engineer
Eng 3 can bring OES Hazmat rig if needed.
What are the three control zones in Hazmat?
- Exclusion Zone (Hot Zone): area immediately around the spill where contamination will occur
- Contamination Reduction Zone (Warm Zone): surrounds the exclusion zone, this is where decon is
- Support Zone: safe, free of contamination, ICP, staging, medical treatment
These zones help manage safety and decontamination during a Hazmat incident.
What shall the first arriving CCCFPD resource do upon arriving at a Hazmat scene?
Establish command and isolate/deny entry.
This is crucial for ensuring safety and managing the incident effectively.
Initial attempts to identify the material shall be made from a safe distance and from where?
- Uphill
- Upwind
- Upstream
This approach minimizes risk to responders during initial assessments.
What are the two types of decon?
- Emergency: remove contaminants from a victim or rescuer when a life-threatening injury or condition exists prior to technical decon being established
- Technical: planned decon set-up prior to entry into the Hot Zone
These types of decontamination are essential for safety in Hazmat situations.
Who is in charge of Decon?
A non-Hazmat captain could be assigned this role: Decon Team Leader.
This person oversees the decontamination process.
Persons working in Decon must be dressed, at a minimum, _______.
one level of protection below persons exiting the hot zone
This ensures safety while managing decontamination.
What is the leading cause of accidental death in the US?
CO - 1500 deaths a year
Carbon monoxide poisoning is a significant public health concern.
CO is a product of what?
Incomplete burning of any material containing carbon such as wood, gas or other fuels.
Understanding the sources of CO is crucial for prevention.
What are the properties of CO?
- Colorless
- Odorless
- Tasteless gas
These properties make CO particularly dangerous as it can go undetected.
What are the mild and serious signs and symptoms of CO poisoning?
- Mild: nausea, dizzy or headaches, flushed face
- Severe: unconscious, respiratory arrest
Recognizing symptoms early can save lives.
What does CO do to the body?
Carbon monoxide enters the body by respiration, displaces oxygen in the blood, and deprives the heart, brain, and other vital organs of oxygen.
This mechanism explains the dangers of CO exposure.
What are the 3 levels of spill
Level 1- small handle with fros
Level 2- requires hm87
Level 3- multi jurisdictional
