CEN WA 43 AND 44EUROPEAN DIRECTIVES FOR DEFENCE & PROTECTION OF
BUILDINGS & VICTIMS FROM TERRORIST CBRN EVENT

The Hazard
• Toxic atmospheres• Fire and smoke• Explosion (dust)• Terrorism CBRN• Pandemic• Industrial accident
www.hazmathood.com3
The risk
• Current focus on victim support• No current protection for victims• No protection for potential victims• Emergency services will be overloaded• Loss of citizen confidence post 1st event
www.hazmathood.com4
The threat
• Terrorism with us for 2 generations• Only a matter of time for dirty bomb• All business have fire alarms and procedures• Buncefield Chernobyl Bhopal• Asbestos dust in most pre 1999 buildings• Travel issues
www.hazmathood.com5
Vulnerability assessment
• 73% of fire victims die from smoke inhalation• 3 breaths of smoke unconscious• 53% of 9/11 victims have new lung problems• 11% of 9/11 victims suffered eye injury• It was illegal to issue PPE to potential victims

Government awareness
• Go in Stay in Tune in• Fire services equipped with decontamination• Temporary mortuaries enlisted• Freezer lorries engaged• Power stations and waste disposal crematorium• 200,000 body bags purchased• 8000 police trained in terrorism CBRN response

Victim protection
Lungs filled with contamination can’t be washed
www.hazmathood.com8
Wearing a protective hood through toxic atmosphere during evacuation is part of the new EEC new
guidelines and standards CEN WA 43
Gap analysis
• No time to assess hazards or risk• Victims use is not occupational• No time for training or fit testing• Cost and storage issues• Required to travel from “Hot Zone” to safety• 80 -20 Rule strip and wash ignores lungs
www.hazmathood.com9
The problem
• Potential victims not protected • Illegal to issue protection PPE 2002 regs • PPE regulations for occupational use only• Victims could never be protected • All resources on helping the victim• No planning to protect the victim

In an emergency you have no time to make assessments

European Solutions 2010
• New Guidelines & Standards CEN WA 43-44• Adopted by BSI • Duty holders identified• Standards of protection recommended• Victims and potential victims protected • Initial responders protected

Duty Holders
• Employers• Facility and Security managers• Venue and large public issues• Travel & passenger safety• Visitors and trespassers

Standards
• BSI British Standards Institute

• ISO ISO/TC 223 Jan 2006 investigating
• CEN European Committee standardisation

Respirator fit testing
• Cannot be worn with beard, spectacles• Leaks with beard growth• Leaks when speaking or moving• Leaks at perimeter seal due to filter efficiency• Better filtration increases leakage

Breathing resistance
• Resistance to inhalation does not exceed 15 mm water at air flow rate of 30 liters per minute.
• Resistance to exhalation does not exceed 5 mm water at air flow rate of 30 liters per minute.

Accumulation of CO2
• After 10 minutes of use, accumulation of Carbon Dioxide does not exceed 3% above the average human concentration of any wearer without the mask. (NIOSH Statement of Standard for CBRN Respirator, September 30, 2003, paragraph 3.4.2 requirements).
• The CO2 data recorded for the last 5 minutes took into account the last 5 breaths, that were mathematically compared to the CO2 accumulation found on the subject tested prior to use of the mask.

Respirator fit
• Different sizes• Fit testing requirement • Training requirement• Maintenance requirement • Inspection training requirement• Filter choices
20

New EEC recognised PM 750
• One size will fit 90% of the population over the age of 6 years, from 5% of the lower level, up to 95% of the higher level.
• The twin seal around the neck provides the single point diametrical closure.
21

Communications
• Frontal communication – the mask does not hamper quality of visibility more than 70%.
• The requirement is for movement of the head sideways and upwards and downwards.
• Verbal communication – speaking and hearing – for a distance of 2 meters between two users.
• The use of cellular telephone is possible whilst wearing the mask.
