The Dangers of Using Explosives in Construction

In the construction industry, explosives are commonly used for large-scale operations such as rock blasting, road construction, dam building, and the demolition of old structures.
While highly effective, the use of explosives carries significant safety risks that must be carefully managed.

At Worksafe Indonesia, we believe that understanding and controlling the dangers of explosives is essential to protect workers and surrounding communities.

Major Hazards Associated with the Use of Explosives

1. Uncontrolled Explosions

Improper handling or detonation of explosives can result in explosions larger than intended.
Risks:

• Serious injuries or fatalities to workers.

• Damage to nearby structures and infrastructure.

2. Flying Debris

Explosions can launch rocks, metal fragments, or debris at high speeds.
Risks:

• Fatal injuries from high-velocity projectiles.

• Endangerment of people outside the blast zone.

3. Ground Vibrations and Shockwaves

Explosions generate powerful ground vibrations and air shockwaves.
Risks:

• Cracks and structural damage to nearby buildings.

• Disruption of underground utilities and local ecosystems.

4. Toxic Gas Exposure

Some explosives release toxic gases such as carbon monoxide and nitrogen oxides.
Risks:

• Poisoning risks for workers and nearby residents.

• Long-term health hazards with repeated exposure.

5. Misfires

Unexploded charges remain hazardous after a failed detonation.
Risks:

• Unexpected explosions during evacuation or cleanup.

• High risks for rescue teams and maintenance workers.

Key Safety Measures for Using Explosives

✅ Only Certified Personnel Should Handle Explosives
All blasting operations must be performed by trained and licensed professionals.

✅ Safe Storage and Transportation
Explosives must be stored securely and transported following strict safety regulations.

✅ Comprehensive Blast Planning
This includes risk assessments, evacuation procedures, and notifying surrounding communities.

✅ Regular Equipment Inspection
All detonators and firing devices must be tested before use to ensure proper functioning.

✅ Strict Access Control
The blast area must be completely cleared of unauthorized personnel before detonation.

✅ Gas and Waste Management
Proper ventilation systems should be installed to eliminate hazardous gases post-blast.

Conclusion

The use of explosives can significantly accelerate construction projects, but the associated risks must never be underestimated.
Strict safety protocols, the use of qualified personnel, and continuous training are essential to prevent fatal accidents.
