The Function of Safety Barrierss
The use of controls or barriers toprotect the people fromthe hazardsis a core principal of safety.
Barriers are employed to serve two purposes; to prevent release of hazardous energy and to
mitigate harm in the event hazardous energy is released. Energy is defined broadly as used here,
and includes multipleforms, for example; kinetic, biological, acoustical, chemic al, electrical,
mechanical, potential, electromagnetic, thermal, or radiation.

The dynamics of accidents may be categorized intofive basic components, illustrated in Figure
1-6: 1) the threator triggering action or energy, 2) the prevention barrierbetween the threat and
the hazard, 3) the hazardor energy potential, 4) the mitigation barrierto mitigate hazardous
consequences towards the target, 5) the targets inthe path of the potential hazard consequences.
When these controls or barriers fail, they allow unwanted energy to flow resulting in an accident
or other adverse consequence.


The objective is to contain or isolate hazards though the use of protective barriers. Prevention
barriers are intended to preclude release of hazards by human acts, equipment degradation, or
natural phenomena. Mitigation barriers are usedto shield, contain, divert or dissipate the
hazardous energy if it is released thus precluding negative consequences to the employees or the
surrounding communities. Distance from the hazard is a common mitigating barrier.
Barrier analysis is based on the premise that hazards are associated with all accidents. Barriers
are developed and integrated into a system or work process to protect personnel and equipment
from hazards. For an accident to occur the design of technical systems did not provide adequate
barriers, work design did not specify use of appropriate barriers, or barriers failed. Investigators
use barrier analysis to identify hazards associated with an accident and the barriers that
should/could have prevented it. Barrier analysis addresses

Hambatan dikembangkan dan terintegrasi ke dalam proses sistem atau bekerja untuk melindungi personil dan peralatan dari bahaya. Untuk kecelakaan terjadi desain teknis sistem tidak memberikan cukup hambatan, pekerjaan desain tidak menentukan menggunakan hambatan yang sesuai, atau hambatan gagal. Penyelidik menggunakan analisis penghalang untuk mengidentifikasi bahaya yang terkait dengan kecelakaan dan hambatan yang harus/dapat dicegah ini. Penghalang analisis alamat
