This law, enacted in 2018, strengthens compliance with
occupational safety and health standards and expands
the rights and responsibilities of workers and employers
in ensuring workplace safety
The Occupational Safety and Health Standards Law (RA 11058)
This is a set of technical standards and guidelines for
electrical installations in the Philippines. It ensures
electrical safety in various settings, including
residential, commercial, and industrial premises.
Philippine Electric Code
This code outlines safety standards and requirements for fire
prevention and protection. It covers topics such as fire
prevention, firefighting equipment, building design, and
emergency exits.
Philippine Fire Code (PD 1185)
This code sets safety standards for the design and
construction of buildings and structures. It includes
provisions related to structural integrity, fire safety, and
accessibility for persons with disabilities.
Philippine Building Code (PD 1096)
This law addresses the safe management,
transportation, and disposal of hazardous wastes,
particularly in industrial and commercial sectors. It
aims to protect human health and the environment.
R. A. No. 6969 - Hazardous Waste
Management Act
While primarily focused on environmental protection, this code
includes provisions related to safety standards for activities that
may have environmental impacts, such as mining and
industrial operations.
Philippine Environment Code (PD 1152)
is a cross- disciplinary area concerned with
protecting the safety, health and welfare of
people engaged in work.

Type of corrosion:
Copper and steel tubing are joined in a domestic water heater, the steel will corrode in the vicinity of the junction
Galvanic corrosion
Localized form of corrosion that creates small deep holes, or pits on the surface of the material
Pitting corrosion
Often caused by the presence of aggressive chemicals or localized difference in the environment
Pitting corrosion
Occurs in confined spaces such as gaps or crevices between metal surfaces where oxygen and other chemicals are limited
Crevice corrosion
Common in seawater or other chloride-rich environment
Crevice corrosion
Occurs when a metal is exposed to a corrosive environment and is under tensile stress
Stress corrosion cracking
Type of corrosion:
Season cracking and caustic embrittlement of mild steel
Stress corrosion cracking
Occurs at the interface between two surfaces that are subjected to cyclic loading or vibration
Fretting corrosion
Cause damage to metal components such as bolts and bearings and lead to failure
Fretting corrosion
Occurs when a metal surface is exposed to a corrosive environment and is also subjected to mechanical erosion such as from flowing liquids or particles
Erosion corrosion
Result in accelerated corrosion and damage to metal
Erosion corrosion
Materials where erosion corrosion occur
Ship propellers
Hydraulic turbine
Pump impeller
Diesel engine cylinder
Gradual destruction of materials by chemical or electrical reaction with their environment
Corrosion
Earliest record of corrosion control from ancient Egyptians
Electroplating
Coating metal objects with a thin layer of gold or silver to protect them from corrosion
Electroplating
Placing metal object in a solution of gold and silver salt and then passing an electric current through it to deposit a thin layer of the precious metal onto the surface
Electroplating
Heating the metal to high temperature and then quenching it in oil or water to create thin layer of oxide on the surface of the metal that would help protect it from further corrosion
Bluing
Period of significant advancement in corrosion control
Industrial revolution
Contained high percentage of chromium which formed protective oxide layer on the surface of the metal
Stainless steel
Considered Japan’s greatest swordsmith from the Kamakura period 14th century
Masamune
A corrosion resistant copper nickel alloy
Monel metal
Corrosion can increase this by requiring frequent repairs or replacements of affected component
Maintenance cost
Corrosion related failures can cause unexpected ____ which can result in lost production, decreased efficiency and reduced profitability for businesses
Downtime
Corrosion can also increase ______ as it cause friction and resistance in moving parts leading to increased wear and tear on equipment and higher energy usage
Energy consumption
Corrosion can compromise _____ of infrastructure and equipment leading to potential collapse or failure
Structural integrity
Corrosion can impose ____ if it affects system that handle water, chemicals or other hazardous materials
Health risk
Corrosion can increase the ____ especially in industrial settings where flammable materials are present
Risk of fires (fire hazards)
By implementing _____,______,_______, businesses and organizations can reduce the risk of corrosion related problems
- Regular inspection
- Maintenance
- Upgrades
