Operational Examplesand Insights

Waste Fire Objectives
What are your objectives Process to guide your response First objective is always to protect and
provide a safe working environment
Now What is the next objective? Smoke/Suppression/Contain/Cost
For ExampleLandfill Fire in Panama
3
Cerro Patacon LF
Panama City Landfill20 + year operational history~ 7 million tons of waste in- place1,200 Tons Daily/24 hours a dayLast bench/lift did not have a soil cover

Landfill Issues
5
Landfill Fire March 19 the largest landfill in Panama was set
ablaze. While it is not official, apparently there were three
separate fires The landfill’s final cell (~200,000 cy) had no soil cover
to prevent the spread Slopes around 1.5 to 1 Add 15 to 25 mph trade winds that blow every day
and evening during the dry season 25 to 30 acres of burning trash
6
Smoke Impact?Landfill less than 5 miles from the CityThe City has a population of 880,691 with a total
metro population of 1,272,672
7
Prevailing Winds - Yes
Smoke plume into the population center

Officials on March 21st

Request for AssistanceWhat is the objective?
Recommendations
Use ICS [Only Fire] Set Priority
Eliminate smoke impacts to the metro population Objectives
Provide for HS for site personnel Contain the fire Locate and Purchase Class A Foam Use soil and foam and work in tandem
11
Process
12
Status
75% Controlled the fire by Sunday Monday elected to use explosives to
“collect the methane” and blow out the south slope
13
OK We Will Go
14
Arrival
All Resources Released 35 to 40 hotspots remaining Project/Site given back to the LF operator No site information available No ICS No foam Now what?

Second- H&S Plan
Should account for all the potential exposures and site hazards
Communications Hospital Locations Emergency Numbers Air Sampling Procedures Respiratory Issues Work Zone (Cold, Warm, Hot)
20
Third - Respirator Plan
Required Must account for multiple hazards based on
types of waste Define your work zones and have real-time
monitoring SCBA, Respirator, N95, real-time monitoring
21
Respiratory Equipment
22
Respirator
Air-Purifying Respirators Will Protect from particulates, dioxins, acid
gasses with limits, metals Will not protect from CO, H2S or Low O2
23
SCBA
Limitations
Inter operability Different departments Different users Breathing/Operating Times (30 m/60m/8hr) Fill Requirements Training and Certs
24
Tracy Suppression –Supplied Air
$411,000/5 days No contaminated water was generated 770,000 gal of water / 990 gal of foam $18 Million (US) to Remove
25
Supplied Air Ground
26
Supplied Air Equipment
27
Warm Zone Firefight with Real-Time Air Monitoring
28
Use of Personal Gas Monitor Technique developed in the field to reduce
exposures to hazardous gasses/chemicals from waste fires
Uses CO as an indicator of other byproducts of combustion
Allows work to be conducted in the warm zone without respirators, SCBAs or supplied air
29
Real Time Air Data
Photo Ionization Detector (PID) Particulate VOC,CO,H2S, CH4, other gasses
30
Personal Gas Meters Gasses to monitor based on site conditions The meter shall be intrinsically safe Look for water resistant models; Should clip or attach at breathing zone; Verify regulatory alert/alarm levels (e.g., STEL) Decide on disposable vs. calibrate type

37
PPE at a Waste Fire
Everyone in the hot and warm zone should be out fitted with the appropriate fire ground personal protective equipment (Bunker/Nomex®)
This includes operators of equipment

Equipment Zone and Rescue
How do you perform a rescue from an
excavator?
Blind and Kill Zones
42Clothing and Rescue
43
Equipment Safety
Minimum of two pieces of equipment Rescue potential, you NEED at least two
Prefer enclosed cabs Pro: Operators are more protected Con: Operators are more aggressive
44
Bottom Line for Waste Fires
Wear appropriate respiratory protection as directed by an industrial hygienist
Breathing air via a SCBA or supplied air should be used if you are in an area of smoke and/or H2S, CO
Wear fire ground PPE Exposure to visible smoke SHOULD BE
AVOIDED without respiratory protection Portable CO monitors can be used to delineate
the hot zone from warm
LF Suppression Summary
Pre Plan / LCES/ Health and Safety Plan/ Respirator Plan Use available resources Manage your water Monitor personnel and work zones ► AVOID SMOKE Have a stock pile of soil available at all times
