Physical Forms & Entry Routes
This solid form becomes hazardous when inhaled into the lungs.
dust
This dust type (<100 μm) affects the nose, throat, and upper airways.
Inhalable dust
“first line” non-specific system includes skin and mucous membranes.
Innate immunity
This document outlines steps in the first minutes of a disaster to protect life, property, and environment.
ERP
Compared to liquids or gases, this physical form is least likely to enter the body
solids
This dust type (<10 μm) reaches the alveoli and causes long-term lung disease.
respirable dust
white blood cells produce antibodies in the adaptive response.
B cells
Give one reason why an ERP is important
legal, safety, damage control, environment, business continuity
These airborne droplets formed from liquids can be toxic when inhaled.
vapour
Cutting or drilling tiles releases this harmful dust linked to silicosis.
silica
The immune system reacts slowly at first but faster on re-exposure
adaptive immunity
Two things that improve ERP effectiveness: staff are ______ and take part in regular ______.
Well trained / drills
Name two factors that affect inhalation risk of airborne hazards.
concentration
solubility
exposure time
Give one control method to reduce respirable dust exposure.
wet cutting
ventilation
RPV
Solvents and mercury are examples of these chemicals that impair the nervous system, leading to narcosis or epilepsy.
Neurotoxin
Name two roles that should be identified in an ERP’s responsibilities section.
notifier
first aider
assistant to first aider
This toxic gas found in confined spaces causes sudden collapse at high levels.
Hydrogen sulfide
Name one sampling method/device for inhalable and respirable dust.
inhalable sampler
Give two components of ERP containment/isolation planning
shutdown systems, secondary containment, fire doors
