5.2 Unsafe Acts and Unsafe Conditions

5.2 Unsafe Acts and Unsafe Conditions

Supervisory focus: Incidents almost never begin with the injury. They begin with visible precursors—people taking shortcuts and workplaces that make those shortcuts easy. Level 3 supervisors must see both, correct both, and run observation programs that improve reality rather than only fill forms.

Definitions That Drive Action

Rule of thumb: If you can photograph the defect without a person in the frame, it is usually an unsafe condition. If the risk appears only when someone chooses a method, it is usually an unsafe act. Many scenes contain both: a missing guard (condition) plus a worker reaching into the danger zone (act).

Why Both Matter in Causation

Classic accident models (and Nigerian incident reports from construction, manufacturing, and oil and gas) show that serious events typically need a chain:

1. An unsafe condition creates opportunity (unguarded coupling, wet floor, live temporary cable).
2. An unsafe act places a person in the energy path (reaching in, rushing, ignoring a barrier).
3. A trigger releases energy (startup, slip, contact).
4. Weak recovery fails (no emergency stop within reach, no spotter, delayed first aid).

If you only blame the act, the next worker meets the same condition. If you only fix the condition once and ignore acts, shortcuts return. Supervisors own both loops.

Common Unsafe Acts on Nigerian Sites

Watch for patterns, not isolated “bad eggs”:

• Bypassing machine guards or permit controls to “save time”
• Working at height without proper fall protection or on improvised platforms
• Entering excavations without shoring checks or atmospheric awareness where required
• Using damaged electrical leads, overloaded sockets, or homemade junction boxes
• Standing in the line of fire during lifting or vehicle reversing
• Ignoring mandatory PPE in “quick” tasks (grinding without eye protection, welding without screens)
• Driving or operating plant while fatigued after long shifts
• Failing to report near misses because of fear or production pressure

Acts often look rational to the worker under schedule pressure. Your job is to make the safe method the easy and expected method—not to discover courage only after an ambulance is called.

Common Unsafe Conditions

Conditions create the stage for acts:

• Housekeeping failures: scrap steel, cables across walkways, blocked emergency routes
• Defective tools and plant: cracked grinding wheels, leaking hoses, worn lifting slings
• Missing or illegible signs, labels, and energy isolation tags
• Inadequate lighting in workshops and night work areas
• Unstable stacking in warehouses and laydown yards
• Temporary structures and scaffold defects after rain or overload
• Chemical storage without segregation, bunding, or SDS access
• Welfare gaps (no drinking water, extreme heat without rest areas) that drive fatigue and dehydration

Treat recurring conditions as system signals. Three oil spills in one week is not three “careless” acts—it is a containment, maintenance, or procedure failure.

Observation Programs That Work

Paper tours that only tick clean areas teach workers to hide problems. Effective supervisory observation programs share these features:

Planned and unplanned presence

• Planned tours use a route and checklist tied to high-risk areas (lifting zones, electrical rooms, confined-space boundaries, chemical stores).
• Unplanned presence catches real work methods—arrive during the task, not only at the tidy start-of-shift briefing.
• Shift coverage matters: night and weekend crews often see fewer supervisors and more improvisation.

What to observe

1. People — position relative to energy, PPE, communication, stop-work use
2. Plant — guards, leaks, alarms, tags, certification stickers
3. Place — access, egress, housekeeping, weather effects, public interface
4. Process — permits open and valid, isolations verified, gas tests current where required

Balance negative and positive findings

If every observation is a punishment, reporting dies. Recognize correct behavior publicly (proper tag-out, asking for a spotter, refusing unsafe instructions). Positive reinforcement is part of hazard control culture, not soft management.

Coaching Versus Discipline

Not every unsafe act is willful misconduct:

ISPON Level 3 expects supervisors to understand that discipline without fixing conditions breeds cynicism, while endless coaching without accountability for willful violations breeds chaos. Apply both with evidence and consistency.

Converting Observations into Control

Use a simple close-out cycle after every meaningful observation:

1. Make it safe now — stop, barricade, isolate, remove people from the line of fire.
2. Classify — act, condition, or both; assign hazard type.
3. Assign — named owner, realistic due date, resources.
4. Verify — supervisor confirms the fix in the field, not only on WhatsApp.
5. Learn — share at the next toolbox talk; look for similar conditions elsewhere.

Link Forward to HEMP and Investigations

Unsafe acts and conditions are the raw material of later HEMP assessments and incident investigations. Clean observation data—specific, dated, classified—makes root-cause work honest. Vague notes such as “worker careless” help nobody. Precise notes such as “fitter reached past missing coupling guard on Pump P-12; guard removed two days earlier and not replaced” enable real prevention.

Build the habit: see it, name it (act vs condition), fix exposure, follow through. That habit is the daily face of supervisory hazard identification.
