Video Summary - (안전교육) 안전작업 수칙

Main ideas / lessons conveyed

Accidents often come from tiny neglected details. Risk is higher on industrial sites than in everyday life, but most accidents can be prevented through proper safety checks before work starts.
Safety work must begin before work begins via pre-work safety inspections that identify and remove potential risk factors.
Korea South-East Power organizes safety management through seven key systems, covering worker alert/call behavior, permits, signage, equipment, inspections, and worker responsibilities.
A strong safety culture is built through strict enforcement mechanisms (notably “one-strike-out” and “two-strike-out” rules), plus worker empowerment to stop work when danger is imminent.
Daily safety practices focus on PPE use, fall prevention, prohibitions on alcohol/smoking, controlled-area entry rules, and following supervisor instructions.
Chemical safety emphasizes Material Safety Data Sheets (MSDS): posting, labeling, training, and maintaining documentation.
Safety also depends on providing and correctly using safety equipment, plus formal authorization via safety work permits and ongoing patrol/inspection plans.
Workers have legal obligations to comply with required safety and health measures under the Industrial Safety and Health Act.

Detailed methodology / instruction lists

1) Pre-work safety inspection (before commencing work)

Identify potential risk factors before starting work.
Eliminate those risk factors.
Ensure inspections are performed properly because:
- Industrial sites have a higher probability of accidents than normal environments.
- Proper pre-work inspections can prevent most accidents.

2) “Seven aspects” of safety management (as described)

Worker constant alert system
Worker safety call system
Safety work permits
Attachment of safety and health signs to hazardous facilities
Provision and management of safety equipment
Safety inspection and patrol plans
Workers’ accident prevention duties

3) Worker enforcement rules: first and second “strike-out” systems

A. One-strike-out (expulsion on a single violation)

Applied when:

Safety instructions from:
- safety managers,
- dedicated safety police, or
- construction supervisors are not followed
A safety accident occurs or is caused in the workplace

Examples given (violations / incidents):

Drinking on site
Breathalyzer result ≥ 0.05
Smoking in a designated smoking area violation context
Operating heavy equipment without authorization (e.g., forklifts, cranes)
Failing to fasten safety hooks when lifting objects when devices are insufficient
Entering controlled hazardous areas without permission
Endangering fellow workers
Failing to wear required safety equipment on site

B. Two-strike-out (stricter after two detections)

Rules:

Caught once → entry prohibited for 2 days
Caught twice → entry completely prohibited for the entire construction period

Examples given:

Failure to observe safety rules/regulations
Vehicle traffic safety violations:
- illegal parking
- speeding
Leaving the driver’s seat when using heavy equipment without removing the ignition key
Violations of:
- Enforcement Decree of the Industrial Safety and Health Act
- Rules on Standards

4) Worker Safety Call System (stop-work authority in imminent danger)

Definition / purpose:

A system aligned with Article 26 of the Industrial Safety and Health Act (Suspension of Work, etc.)
Allows a supervisor or partner company worker to:
- immediately stop work
- take necessary measures (including evacuating workers)
Goal: manage imminent industrial accident risk before resuming work.

When a safety call is required (examples):

Supervisory department has not provided safety/health information about the work
Safety/health facilities are missing in risk areas such as:
- landslides
- fire
- explosion
- falls
- falling fires
Design changes are needed due to high disaster risk (e.g., collapse of temporary structures)

Process described (operational steps):

Partner company worker reports a dangerous situation or requests work stoppage to the safety department.
Workplace safety management department verifies the hazard and orders a work stoppage.
Construction company supervisory department removes risk factors to make the site safe.
Site safety management department confirms safety has been secured and notifies workers.
Subcontractor workers who receive the notification resume work.

5) “Five essential safety rules” workers must follow and check

Wear PPE on site
- e.g., safety helmets, safety shoes, safety goggles
Use a safety harness and fasten the hook when fall risk is 2 meters or more
No drinking or smoking on the work site
No entry to hazardous areas, such as enclosed spaces where oxygen concentration measurement has not been initiated
Follow instructions from the safety manager or construction supervisor

6) MSDS (Material Safety Data Sheet) system for hazardous chemical safety

Core purpose:

Enable chemical handlers to protect themselves by informing them of significant chemical risks.
Called MSDS (Material Safety Data Sheet), based on the abbreviation of the English term.

What MSDS must include / address:

Display/post:
- chemical name
- composition
- contents
- safety & health handling precautions
Provide warning labels
Provide worker training (classification, procedures, PPE, emergency measures)

Training content (as described):

classification and volatile nature of chemicals
work procedures
PPE requirements
emergency measures in case of an accident

Where MSDS must be placed:

In the most visible location to workers
Specifically within work process areas where target chemicals are handled and where there is risk of:
- safety accidents
- occupational diseases

Requirements for transferring/providing chemicals:

The container/packaging must be labeled with:
- chemical name
- pictogram
- signal word
- hazard statement
- precautionary statement
- supplier information
Goal: workers can identify chemical hazards at a glance

Common compliance issues listed (and implied corrective necessity):

MSDS data not kept readily available (including often-overlooked substances like welding oil, paint, diesel fuel, kerosene, oils)
Missing warning labels on chemical containers
Training not provided (training records must be preserved)

Examples of chemicals mentioned for training:

powder coatings containing titanium dioxide
boiler cleaning agents containing phosphoric acid
welding flux
atlan oxide (as stated)

Where to verify/create MSDS content:

Use the Korea Occupational Safety and Health Agency chemical substance information website
Search by substance name to create MSDS warning labels

7) Provision and management of safety equipment (process + definition)

System description:

A one-year process to provide construction-required safety equipment to workers.
Steps include:
- prior confirmation with the construction supervisor
- review by the safety management department person to determine whether equipment is subject to safety management costs
The ordering department must:
- record distribution in a safety equipment distribution log per department
- keep internal records of results

What protective equipment means (as defined):

A device that:
- blocks external hazardous factors affecting part/all of the worker’s body
- reduces impact
- prevents industrial accidents or minimizes the severity/magnitude of harm

Selecting the right PPE:

Choose equipment suitable for the specific hazardous factors.

Examples of PPE listed:

safety helmets, dust masks, anti-freeze masks, air-supplied masks, powered respiratory protection
safety shoes, protective suits, safety belts, safety gloves
safety shields, hearing protection, safety goggles

8) How to wear major protective equipment (procedural instructions)

A. Safety helmet (procedure)

Check condition:
- body
- fittings
- shock absorbers
- abnormal remnants of jaw muscles (as phrased)
If no issues:
- place on head
- adjust head holder to fit head size
Positioning:
- jaw/side supports positioned on both sides of ears
- tighten to prevent slipping

B. Earplugs (procedure)

Compress by rotating
Insert by pulling ear and inserting fully
After insertion:
- press for about 15 seconds to ensure they do not pop out

C. Dust masks (two types + general fitting checks)

1) Detachable filter/detach/face-filter (as described):

Insert filter into case, press lock until it clicks
Put head strap over head
Wrap front sufficiently around nose/mouth (and tongue as stated)
Tighten neck strap
Hook loop at back of neck
Tighten neck area to fit face
Perform a close-fit test with both hands

2) Face-filtering dust mask:

Flatten mask into cup shape
Bring toward face with head straps hanging downward
Place under chin
One hand holds mask; other pulls head strap to wear
Unfold edges to fit face gaps
Bend nose clip to secure fit over nose
Perform tightness test with both hands to ensure sealing

D. Safety harness (“Geunhye-style”) (procedure)

Place harness on both legs
Lift it up
Place on both shoulders
Finish by:
- fastening chest strap
- hooking hook on the safety belt onto the lifeline
- checking proper wearing/attachment state
If lifeline is horizontal, attach it to the safety harness (as stated)

9) Safety Work Permit (authorization before specific high-risk work)

Definition:

A document where a safety supervisor ultimately authorizes work after verifying site safety conditions.

Approval workflow:

Supervisory department representative:
- creates permit in KOPISIN system
- requests approval
Deputy manager or head of supervisory department:
- reviews safety measures and approves
Head of facility operations department:
- gives final approval after confirming on-site safety measures are implemented

During/after work handling:

Post final approved plan on safety work status board during work
Collect after work ends
Keep original for one year from issuance date of supervision report
Submit copies to safety management department by the 5th of every month

Types of work requiring permits (nine types):

fire
general hazards
confined spaces
excavation
radiation
work at heights
equipment
power outages
diving

Supplementary work permit (as described):

Permits for power outages, excavation, radiation, heavy equipment, and diving
Can be issued separately without issuing fire/general hazard permits

10) Safety patrol and inspection plan (inspection frequency + special cases)

General requirement:

Safety management personnel must inspect the workplace frequently.

Inspection frequency table (as stated):

Safety & Health Management Officer: at least once a week
Safety Officer: at least twice a week
Safety Manager and Safety Inspector: daily
Safety Officer: as needed (as phrased)
Joint safety inspections:
- Safety & Health Management Officer: at least once a quarter
- Safety Officer / Safety Inspector (multiple roles listed): at least once a month

Special cases requiring more frequent inspections:

important construction
ceasefire-related construction (as phrased)
night construction → inspections must be frequent regardless of the table

Co-located workers rule:

If workers/contractors work in the same location:
- inspect and check jointly at least once a day

Records:

Inspection logs must be completed and managed according to relevant forms.

11) Worker legal duties (compliance obligation)

In accordance with Article 6 of the Industrial Safety and Health Act:
- workers must comply with safety and health measures required by relevant parties (e.g., employers, labor inspectors, and the corporation) under the Act.
