Hazard Control
First Responder Awareness Level
First Responders (Awareness Level): workers likely to witness/discover hazardous substance release AND who trained to initiate emergency response sequence by notifying proper authorities of the release
They take no further action beyond notifying the authorities of the release
First Responder Awareness Level
~8 hours of training Similar to OSHA Hazcom (1910.1200) First Responders (Awareness Level)
shall have sufficient training OR have had sufficient experience to objectively demonstrate competency
First Responder Operations Level
First Responders (Operations Level) are workers who respond to releases/potential releases of hazardous substances as part of initial response to the site for purpose of protecting nearby persons, environment, property from effects of the release
First Responder Operations Level
Trained to respond in defensive fashion without actually trying to stop the release
Function: contain release from a safe distance, keep it from spreading, and to prevent exposures
First Responder Operations Level
First Responders (Operational level) shall receive ≥8 hours of training OR have sufficient experience to objectively demonstrate competency
Courses are 16-24 hours with 24 being common
Hazmat Technician Level
Hazmat Technicians respond to releases/potential releases to stop the release
They assume a more aggressive role than Operations, approaching the point of release to plug, patch or otherwise stop the release
Hazmat Technician Level
Technicians receive minimum 24 hours training equal to Operations level AND have competency in assigned tasks for each incident
Hazmat Specialist Level
Hazmat Specialists respond with and provide support to Hazmat Technicians
Hazmat Specialist Level
Duties parallel Hazmat Technician but require more
directed or specific knowledge of various substances upon which they they may encounter
Hazmat Specialist Level
Act as Site Liaison with Federal, State, Local, other government authorities regarding site activities
Receive at least 24 hours of Technician-level training
Incident Command Level
Incident Commanders assume control of the incident scene beyond the First Responder Awareness Level and shall receive at least 24 hours of training
equal to the First Responder Operations Level. They also need competency in Incident
Command systems & requirements
Hazard Control
Hazard Control:INTRODUCTION
Hazardous waste sites & environments pose S&H concerns which could result in serious
injury/death
Hazard Control
Hazard Control:INTRODUCTION
Additional hazards created by
Heavy equipment PPE reducing movement,
hearing & vision
Unpredictability of the site
Other employers
Hazard Control
Safety hazards that may exist at hazardous waste sites
Holes or ditches Failed excavations
Falling objects Sharp/jagged objects
Hazard Control
Safety hazards that may exist at hazardous waste sites
Slippery surfaces Steep grades Uneven terrain Unstable surfaces
Hazard Control
What electrical hazards can pose danger to workers?
Overhead electrical lines Fallen electrical wires Buried cables Electrical equipment (use low-
voltage equipment with ground-fault interrupters and watertight, corrosion-resistant connecting cords)
Hazard Control
Lighting Weather conditions Capacitors
retain a charge
What electrical hazards can pose danger to workers?
Hazard Control
How do hazardous energy control (HEC) procedures protect workers?
Before servicing & maintenance of equipment, OSHA requires control procedures to ensure “Zero Energy State!”
Hazard Control
Lockout device (lock, chain, valve, etc.)
Prevents flow of energy to prevent 1) unexpected start-up of equipment, and 2) unintended release of energy
How do hazardous energy control (HEC) procedures protect workers?
Hazard Control
Tagout
Tag the power source
Administrative control, not engineering control
How do hazardous energy control (HEC) procedures protect workers?
Hazard Control
Establish a program Utilize procedures for affixing
appropriate lockout/tagout devices to power sources
Otherwise disable equipment/machine to prevent unexpected start-up of equipment, or release of stored energy
Requirements under HEC
Hazard Control
Effects of Noise
Noise = Unwanted Sound Heavy equipment creates
harmful noise levels
Hazard Control
Unit of Measure for Sound
Sound intensity = decibels (dB)
Examples
Ticking watch = 20 dB (barely audible)
Jet engine = 130 to 160 dB (painful)
Hazard Control
Implement a Hearing Conservation Program?
OSHA says
A Hearing Conservation Program is required when noise levels ≥8 hour time-weighted average (TWA) sound level of 85dBA
Hazard Control
Engineering & administrative controls must be used if workers are subject to noise >8-hour TWA of 90 dBA
Implement a Hearing Conservation Program?
Hazard Control
Minimize noise
Noise monitoring Audiometric testing Engineering controls (e.g.,
design or retrofit; isolate exposure from workers; acoustical materials)
Hazard Control
Administrative controls (rotate employees, operate offending equipment w/minimum staffing)
PPE (plugs; caps; muffs)
Training
Minimize noise
Hazard Control
Eye/Face Protection
Reasonable probability of injury from Flying objects Glare Liquids Injurious radiation Combination of these hazards
Hazard Control
Eye/Face Protection
Reasonable probability of injury from Glasses – “big chunks” Goggles – “small chunks”
Also mist, vapor, aerosol Shield – see “goggles”
Hazard Control
When projectiles exist, workers must use eye protection that provides side protection
Refer to ANSI Z87.1, et al
Eye/Face Protection
Hazard Control
Requirements of eye and face PPE?
Must be
Distinctly marked to facilitate identification of the manufacturer
Capable of being disinfected and easily cleaned
Hazard Control
Requirements for prescription glasses & contact lens wearers?
Prescription lens wearers need
Eye protection incorporating prescription in its design, or
Eye protection worn over prescription lenses w/o disturbing proper position/integrity/function of either
Hazard Control
The use of contact lenses should
Be considered carefully Comply with the site-specific HASP*
*HASP: Health & Safety Plan
Requirements for prescription glasses & contact lens wearers?
Hazard Control
Eye/face/body flushing
When chemical hazards are present
Eye wash stations - readily available & accessible
Water/flushing solutions - to prevent particles from further injuring eyes
Hazard Control
When is head protection required?
Can
An object strike the head? The head strike an object? The head contact an energized
electrical conductor?
Hazard Control
Head protection must meet all safety requirements (ANSI Z89.1)
Hair must be restrained to prevent snagging on surrounding objects
When is head protection required?
Hazard Control
When is protective footwear required?
Where potential hazards are present from
Falling/rolling objects Objects may pierce the sole Chemical exposure Electrical shock Wet floors
Hazard Control
Recommended types of footwear
Safety toe shoes (hard toe)
Treated shoes Rubber boots or plastic

Skin absorption Cuts, abrasions, punctures Chemical or thermal burns Harmful temperature extremes
Hazard Control
Employers must require workers to use appropriate hand protection meeting all safety requirements
Hand protection
Hazard Control
Select gloves on the basis of
Material being handled
Hazard involved
