Hazardous Waste

Hazardous Waste

- anything which, because of its quantity,concentration, or physical, chemical or infectious

characteristics, may cause, or significantly contributeto an increase in mortality; or cause an increase inserious irreversible or incapacitating irreversibleillness; or pose a substantial present or potentialhazard to human health and the environment when

improperly treated, stored, transported, or disposedof, or otherwise managed

Ignitable, Corrosive, Reactive, Toxic

Effects of Hazardous waste

covered with sores since he was exposed

to toxic wastedump


5/44

The cadmium poisoning

caused softening of the

bones and kidneyfailure. The disease is

named for the severe

pains caused in the

joints and spine

The cadmium was

released into rivers bymining companies in the

mountains


6/44

Hazardous WasteDAO 36

Hazardous wastes

are substances that are without any safecommercial, industrial, agricultural or

economic usage and are shipped,transported or brought from thecountry of origin for dumping or

disposal into or in transit through anypart of the territory of the Philippines.


7/44

Hazardous WasteDAO 36

Hazardous wastes

shall also refer to by-products, side-products,process residues, spent reaction media,

contaminated plant or equipment or othersubstances from manufacturing operationsand as consumer discards of manufacturedproducts which present unreasonable risk

and/or injury to health and safety and to theenvironment.

Any waste thatexhibits one ormore of thesecharacteristics is

consideredhazardous waste

HAZARDOUS WASTES

Toxicity


10/44

Characteristics of

Hazardous Wastes

Toxic Poisonous

Carcinogenic

Mutagenic

Teratogenic

Toxicity Characteristic Leaching Procedure)-a procedure used to simulate the leaching

which a waste will undergo if disposed of ina sanitary landfill and is applicable to liquid,solid and multi-phased sample


11/44

Characteristics of

Hazardous Wastes

Reactive

Unstable under normal conditions andreadily undergo violent change without

detonating React violently with water and create

spontaneously explosive mixtures like toxicgases, vapors or fumes

Capable of detonating


12/44

Reactivity


13/44

Characteristics of

Hazardous Wastes

Corrosive

Acidic or basic with pH greater than 12.5 or lessthan 2.0

Capable of corroding metal such ascontainers,tanks, barrels and drums


14/44

Corrosivity


15/44

Characteristics of

Hazardous Wastes

Ignitable

Applies to any physical state

Any liquid having a flash point of not more than140F/60C

Any of the following solids:

Wetted explosives that when dry are explosives

Self-reactive materials that are liable to undergostrongly exothermal decomposition

Pyrophoric materials (also liquid) that can ignitewithin 5 min after coming in contact with air

The Dirty Dozen

Persistent Organic Pollutants

Organic chemicals (mostly synthetic) that

remain intact in the environment for long

periods, become widely distributedgeographically, accumulate in the fatty tissue

of living organisms and are toxic to humans

and wildlife.

POPs circulate globally and can cause damage

wherever they travel


21/44

The POPs list: Dirty Dozen

DDT Heptachlor

Endrin Mirex

Dieldrin Hexachlorobenzene

Aldrin Polychlorinated Biphenyls (PCBs)

Toxaphen Dioxins

Chlordane Furans


22/44

Household Hazardous Wastes

Products containing hazardous material should say poison, toxic ordanger

In the kitchen:

Aerosol cans, cleaners, floor care products, metal polish and metal

cleanersIn the bathroom:

Cleaners, disinfectants, hair relaxers, medicines, nail polish and polishremovers.

In the garage/workshop:

Auto batteries, brake fluid, degreasers, gasolines, kerosene, motor oil, oil

filtersOthers:

Computer scraps, busted fluorescent lamp, expired medicines.

Exempt Wastes from

RA 6969 Coverage

Garbage from domestic premises & households

Treated industrial or commercial wastewater that aredisposed of on-site through the sewerage system

Industrial & commercial solid wastes that do not contain

prescribed hazardous wastes as listed Materials from building demolition except those that contain

asbestos

Septic tank effluent & sewage from domestic sources

Untreated spoils from mining, quarrying, & excavation works

From Cradle to Grave waste

management system

the GENERATOR has theresponsibility until the waste has

been disposed of properly in anenvironmentally sound way and isliable in case of spill or illegaldisposal

RULE OF THUMB


37/44

ID of a chemical

A technical document that providesinformation of that chemical

A simple and precise descriptions ofchemical properties

can be used as an instruction to thechemical substance

a basic tool for management of thechemicals.

= ID / birth

certificate

= MSDS or SDS

What is Material Safety Data Sheet ?


38/44

MSDS include information such as,

physical data

health effects

first aid

reactivity

storage

disposal protective equipment, and

spill/leak procedure.



39/44

MSDS are meant for:

Employeeswho may be occupationally exposed to a

hazard at work

Employers who need to know the proper methods forstorage, etc.

Emergency responderssuch as fire fighters, hazardousmaterial crews, emergency medical technicians, andemergency room personnel



40/44


1. Eliminate of reduce waste quantities

2. Reclaim and recycle waste3. Stabilize the waste

4. Apply land disposal method


41/44

Last Words

Pollution Prevention is better than End-of-Pipe

Approach

Cost of cleaning up the environment is greater

than cost of waste minimization.


42/44

Last Words

Everybody on earth is a Polluter and has an

individual impact on the environment.

Every polluter should be responsible for the

pollution he/she causes.

Every responsible polluter should be willing to

pay the price for mitigating his/her impact on

the environment.
