Notable quotes (customized) forengineers:

A gram to

prepare

is better than

a ton to repair.

Factor of Safety (FS)

In engineering, FS is the ratio of

calculated strength of a member to

the predicted structural demand that

will be applied upon it when the

member is part of the structure.

1. INTRODUCTION TO SAFETY


6/33

Safety in Construction

Safety should be given

considerable factor (of safety) for

the importance it may impart tothe project, after all, safety

consideration is always part of

engineering, from planning, to

construction, and to occupancy or

operation stages.

What is Safety?Safety is the control of circumstances

or conditions to prevent harm topeople, or minimize damages andlosses to properties.

Major problems related to worksafety

Low priority given to work safetyconcerns

Lack of awareness and education on

work safety

Lack of trained personnel Weak enforcement of safety

standards

Lack of safety facilities

Safety programs are not reliable dueto low compliance.

Why Safety and Health?

Adopted from OSHC


19/33

Accident is an unexpected,unforeseen, unplanned andunwanted occurrence orevent that results in harm topeople, cause damage or

loss to properties.

What is an accident?


20/33

What is an incident?

An unexpected, unforeseen, unplannedand unwanted event, which under

slightly different circumstances, COULDHAVE RESULTED in harm to people,cause damage or loss to properties.


21/33

AN ACCIDENT IS ALWAYS

AN INCIDENT,

BUT AN INCIDENT IS NOT

ALWAYS AN ACCIDENT


22/33

Types of accidents in construction sites:

Struck against rigid structure, sharp or

rough objects

Struck by falling or flying objects, sliding ormoving parts

Caught in or between objects

Fall on same level

Fall on different levelsExposure to - noise - electricity - toxics -temperature extremes - high pressures -radiation - fires


23/33


24/33

- the human action that departs from

a standard or job procedure orcommon practice, safety rules,regulations or instructions

Unsafe Act


25/33

- the physical or chemical property

of a material, machine, or theenvironment which could result ininjury to a person, damage or

destruction to property or otherform of losses

Unsafe Condition


26/33

Studies show that :

2% of accidents are non-preventable 98% of accidents are preventable

88% constitute unsafe acts

10% due to unsafe conditions

Unsafe Acts vs.

Unsafe Conditions


27/33

- any existing or potential condition

in the workplace which by itself orby reacting with other variablescan result in the unwanted effects

of injuries, property damage,death and other losses

HAZARD


28/33

Most of them, by controllingthe hazards in this order:

1. Engineering Control

2. Administrative Control

3. Personal Protective Equipment


29/33

Last line of

control/defense

2. Administrative Control:

Exposure time limitations Safe work practices

Alarms and warning signs

Training and education

3. (Point of contact)

Personal ProtectiveEquipment

Three areas where hazards can be controlled:

SOURCE RECEIVERPATH

1.(Pre-contact) Engineering Control : Elimination/minimization

Enclosure of the hazard

Redirection of hazard

Systems to Control Unsafe Conditions


30/33

Systems to Control

Unsafe Condition

Good Housekeeping

Preventive Maintenance

Engineering Control

Administrative Control


31/33

Systems to Control Unsafe Act

Education and Training

Visual Awareness

Tool Box Meeting

Award/Incentive System

Disciplinary Action

Safety Orientation, Job Instructions

Posters, Signs, Bulletin Board

A 10-15 minute on-the-job meetings

Positive Approach

Negative Approach


32/33

Hierarchy of Safety:

1. ELIMINATE the hazard2. If not practical, PREVENT

3. If not practical, CONTROL
