SITE SAFETY / HSE QA / QC COMMUNITY RELATIONS
Roles and Responsibilities in Construction Site Safety: A RACI Framework
Most site-safety failures are not caused by a missing rule — they are caused by a missing owner. When an incident investigation traces back the root cause, it very often lands on a blurred line of accountability: everyone assumed someone else was watching the permit, chasing the toolbox talk register, or fielding the resident's noise complaint. This guide sets out a clear, RACI-based division of safety responsibility across four core site roles — the Project Director, the Site OHS Officer, the Community Liaison Officer (CLO), and the workforce — anchored in the Bangladesh Labour Act 2006, the Bangladesh Labour Rules 2015, BNBC 2020, and the ISO 45001:2018 management-system structure that increasingly underpins contractor safety plans in Bangladesh.

Why Role Clarity Is a Safety-Critical Control
A safety organogram is not paperwork — it is a control in its own right. ISO 45001:2018, Clause 5.3 ("Organizational roles, responsibilities and authorities"), requires top management to assign and communicate responsibilities for OH&S at every relevant level of the organization, precisely because diffused accountability is a recurring precursor to serious incidents. On a live site, the practical effect of a well-defined role matrix is threefold: it tells the Project Director exactly which decisions cannot be delegated away, it gives the Site OHS Officer the standing to stop unsafe work without needing to escalate every time, and it gives workers and neighbouring residents a single, known point of contact rather than a chain of "not my department" responses.
For a Bangladesh contractor, this matters commercially as well as ethically. Congested urban plots in Dhaka and Chattogram routinely place active construction work within a few metres of occupied housing, shops, and roadways — pushing community liaison from a "nice to have" into a genuine site-safety function that manages dust, noise, vibration, and pedestrian-conflict risk to third parties, not only to the workforce.
Legal and Standards Basis for Site Safety Roles
No single Bangladeshi statute lays out a construction-specific safety organogram in the way this article does; the role structure below is assembled from three overlapping instruments, which should always be read together for a live project:
| Instrument | What It Establishes | Relevance to Roles |
|---|---|---|
| Bangladesh Labour Act, 2006 (as amended) | Employer duties on health, safety, and welfare (Chapters V–VIII); enforcement by the Department of Inspection for Factories and Establishments (DIFE) | Places ultimate statutory duty of care on the employer/occupier — the basis for Project Director accountability |
| Bangladesh Labour Rules, 2015 | Implementing procedures under the BLA, including Rule 75 on adherence to safety provisions during construction | Frames the operational safety-compliance duty that a Site OHS Officer discharges day-to-day |
| BNBC 2020 (gazetted February 2021) | Structural, fire, and occupational safety provisions for the building sector | Technical basis for site safety measures the OHS Officer inspects against |
| ISO 45001:2018 | Voluntary OH&S management-system standard; Clause 5.3 on roles/responsibilities, Clause 5.4 on worker consultation | Provides the RACI/accountability logic used throughout this article |
Site Safety Accountability Structure
The four roles sit in a deliberately short reporting chain so that a hazard identified at worker level reaches decision-making authority in as few steps as possible.
The Four Core Roles, in Detail
1. Project Director — Overall Accountability for Safety Compliance
The Project Director holds ultimate accountability, not day-to-day execution. Under the Bangladesh Labour Act 2006's employer/occupier duty-of-care framework, this accountability cannot be fully delegated even though its tasks are. In practice, the role covers:
- Approving and resourcing the project's HSE plan, budget, and staffing (including whether the Site OHS Officer role is full-time, per BNBC guidance for larger sites)
- Setting and visibly enforcing the site safety policy, including the authority for any competent person to stop unsafe work
- Reviewing monthly safety KPIs (LTIFR, TRIR, toolbox-talk completion rate — see the formulas below) at project review meetings, not only after an incident
- Making the final call on statutory incident notification to DIFE and liaising with the client/consultant on notifiable events
- Chairing periodic management review of the safety management system, per the intent of ISO 45001:2018 Clause 9.3
2. Site OHS Officer — Daily Monitoring, Toolbox Talks, and Incident Reporting
The Site OHS Officer (also titled Safety Officer or HSE Officer depending on the project) is the operational engine of the safety plan. Core duties include:
- Daily monitoring: walking the site each shift to check PPE compliance, scaffold/access condition, housekeeping, and permit-to-work status against active hazardous tasks
- Toolbox talks: delivering short, task-specific safety briefings before each material-intensive or high-risk activity (concreting, rebar fixing, working at height, excavation, hot work) and maintaining a signed attendance register
- Incident reporting: capturing near-misses and incidents on a standard form within the shift they occur, classifying severity, and escalating notifiable events to the Project Director without delay
- Issuing, verifying, and closing out permits-to-work for hazardous activities (see the permit-to-work section below)
- Maintaining PPE stock, training records, and toolbox-talk logs as auditable evidence for both internal review and any DIFE inspection
- Coordinating emergency drills and first-aid provision, and acting as the site's primary point of contact during an incident response
3. Community Liaison Officer — Communication with Residents
On congested urban plots, the CLO manages a category of risk that a purely worker-facing safety plan misses entirely: the safety and goodwill of people outside the site boundary. Typical responsibilities:
- Maintaining a published, working contact channel (phone/notice board) so residents can raise a concern before it becomes a formal complaint
- Logging and tracking every grievance — dust, noise outside permitted hours, vibration, blocked access, damage claims — with a target response and resolution time
- Coordinating advance notice to neighbours before noisy or disruptive activities (piling, concrete pours, night work where permitted)
- Liaising with the Site OHS Officer where a community concern has a safety dimension (e.g., unsecured hoarding, falling debris risk to a public footpath, unguarded excavation adjacent to a boundary wall)
- Feeding recurring complaint themes back to the Project Director as an input to the monthly safety and community-relations review
4. Workers — PPE, Permit-to-Work, and Training
Workers are not passive recipients of a safety plan; the Bangladesh Labour Rules 2015 and BNBC 2020 both frame worker compliance as a duty, not merely an entitlement to protection. Core worker responsibilities:
- PPE compliance: wearing task-appropriate personal protective equipment (helmet, safety boots, high-visibility vest, and task-specific items such as harnesses, dust masks, or eye protection) for the full duration of exposure, not only during inspection rounds
- Permit-to-work discipline: working only under a valid, displayed permit for activities that require one (hot work, confined space, working at height, excavation, electrical isolation), and stopping work if the permit conditions change
- Training and induction: completing site induction before first entry, attending toolbox talks relevant to the day's task, and reporting any training gap to the supervisor rather than proceeding untrained
- Hazard and near-miss reporting: raising unsafe conditions or near-misses to the Site OHS Officer or supervisor immediately, without fear of reprisal — a principle consistent with ISO 45001:2018 Clause 5.4 on worker consultation and participation
RACI Matrix: Who Owns What
A RACI matrix (Responsible, Accountable, Consulted, Informed) makes the division of labour explicit and auditable. Only one role should ever be Accountable for a given task.
| Task | Project Director | Site OHS Officer | Community Liaison Officer | Workers |
|---|---|---|---|---|
| HSE plan approval & budget | A | R | C | I |
| Daily site safety inspection | I | A / R | – | C |
| Toolbox talk delivery | I | A / R | – | R (attendance) |
| Permit-to-work issuance & closure | I | A / R | – | R (compliance) |
| PPE provision & enforcement | A | R | – | R (wear) |
| Incident investigation & DIFE notification | A | R | I | C |
| Resident grievance handling | I | C | A / R | – |
| Advance notice of disruptive works | I | C | A / R | I |
| Worker induction & training records | I | A / R | – | R (completion) |
| Near-miss / hazard reporting | I | R (log & act) | C (if third-party) | R (raise it) |
| Monthly safety KPI review | A | R | C | I |
Safety Performance Formulas & Worked Example
Two standard rate formulas let the Project Director and Site OHS Officer compare performance objectively across months and against industry benchmarks, rather than relying on incident counts alone (which are meaningless without an exposure-hours denominator).
LTIFR = (Number of Lost Time Injuries × 1,000,000) / Total Hours Worked
2) Total Recordable Incident Rate (TRIR)
TRIR = (Number of Recordable Incidents × 200,000) / Total Hours Worked
The 1,000,000-hour base for LTIFR and 200,000-hour base for TRIR (equivalent to 100 workers each working 2,000 hours/year) are the internationally used exposure denominators, allowing sites of different sizes and durations to be compared on a like-for-like basis.
Worked Example
| Average workforce on site | 60 workers |
| Working schedule | 9 hours/day, 26 days/month |
| Reporting period | 12 months |
| Total hours worked | 60 × 9 × 26 × 12 = 168,480 hours |
| Lost Time Injuries recorded in the period | 1 |
| Recordable incidents recorded in the period (incl. the LTI) | 3 |
| LTIFR | (1 × 1,000,000) / 168,480 = 5.94 |
| TRIR | (3 × 200,000) / 168,480 = 3.56 |
Permit-to-Work System Basics
A permit-to-work (PTW) system is a formal, documented control confirming that a hazardous task has been risk-assessed, that controls are in place, and that a named, competent person has authorized work to begin within a defined time window. On BNFEL-supervised sites, activities typically requiring a permit include:
| Activity | Typical Permit Type | Key Control Verified Before Issue |
|---|---|---|
| Working at height (>2 m or per site threshold) | Working-at-height permit | Guardrails/harness anchor points inspected, weather check |
| Excavation & trenching | Excavation permit | Utility clearance, shoring/battering, edge protection |
| Hot work (welding, cutting, grinding) | Hot work permit | Fire watch assigned, combustibles cleared, extinguisher on hand |
| Confined space entry | Confined space permit | Atmosphere tested, rescue plan and standby person in place |
| Electrical isolation | Lock-out/tag-out (LOTO) permit | Circuit isolated and verified dead, lock applied by authorized person |
The Site OHS Officer issues and closes permits; the requesting supervisor and crew are jointly responsible for working strictly within the stated conditions; and any change in scope, personnel, or site condition (e.g., weather deterioration for height work) requires the permit to be suspended and re-verified before work resumes.
Risk & Safety Instructions by Role
- Project Director: Do not treat the monthly KPI review as a formality — a rising trend in near-misses without a matching rise in reporting activity often precedes a serious incident. Ensure the Site OHS Officer has the standing and independence to halt work without needing prior sign-off in an emergency.
- Site OHS Officer: Never issue or extend a permit-to-work from memory or verbally; every permit must be a dated, signed document with defined validity. Cement dust exposure during PPE checks requires the officer's own respiratory protection (minimum FFP2/N95), not only the workers'.
- Community Liaison Officer: Verify claims of property damage (e.g., cracking attributed to vibration) with the Site OHS Officer or a structural engineer before responding — premature admission or denial can both create liability exposure. Keep a dated log of every complaint and resolution.
- Workers: A permit-to-work is void the moment a stated condition changes (personnel, weather, adjacent activity). Stop and report to the Site OHS Officer rather than continuing on the original authorization. PPE that is damaged, expired, or the wrong type for the task must be replaced before work resumes, not after the shift.
- Fire and evacuation: All four roles should know the site's emergency assembly point and alarm signal; the Site OHS Officer is responsible for running and logging periodic drills, and the Project Director for ensuring drill findings are actioned.
This section provides general engineering guidance and does not replace the project's site-specific Health, Safety & Environment (HSE) plan, which should govern all site activities and be read alongside current Bangladesh Labour Act 2006 / Labour Rules 2015 requirements.

Frequently Asked Questions
Who is legally responsible for safety on a Bangladeshi construction site?
Ultimate statutory responsibility sits with the employer/occupier under the Bangladesh Labour Act 2006, which in practice is exercised through the Project Director as the site's senior accountable authority. Day-to-day operational responsibility is typically delegated to a Site OHS Officer, but delegation of tasks does not remove the Project Director's accountability for outcomes.
What is the difference between "responsible" and "accountable" in a safety RACI matrix?
"Responsible" identifies who actually performs or ensures completion of a task (e.g., the Site OHS Officer delivering a toolbox talk). "Accountable" identifies the single role answerable for the outcome (e.g., the Project Director being accountable for overall safety compliance). A task can have several "Responsible" or "Consulted" parties, but only one "Accountable" owner.
Why does a construction site need a Community Liaison Officer for safety, not just PR?
Urban infill sites place work directly adjacent to occupied buildings and public footpaths, creating third-party risks — falling debris, vibration-induced damage, dust, and pedestrian-traffic conflicts — that a worker-only safety plan does not cover. The CLO is the role positioned to detect and communicate these hazards before they cause injury or a formal grievance.
What is a permit-to-work system and when is one required?
A permit-to-work is a formal, time-bound authorization confirming that a hazardous task has been risk-assessed and that controls are verified before work starts. It is typically required for working at height, excavation, hot work, confined-space entry, and electrical isolation — and becomes void the moment a stated condition changes.
How is LTIFR different from TRIR?
LTIFR (Lost Time Injury Frequency Rate) counts only injuries that result in the worker being unable to work their next scheduled shift, expressed per 1,000,000 exposure hours. TRIR (Total Recordable Incident Rate) counts a broader category — every incident meeting a "recordable" threshold, including lost-time injuries, restricted-duty cases, and medical-treatment cases — expressed per 200,000 exposure hours. TRIR is therefore always equal to or higher than the equivalent LTIFR-scale figure for the same site.
