Site Access Authorization Calculator

Enter access details

Provide role, dates, checks, and documents. The calculator returns an authorization decision with traceable conditions and exportable records.

Example data table

Sample scenarios illustrate how inputs influence score, threshold, and decision.

Formula used

This calculator assigns a score from 0 to 100 using weighted checks, then compares it to a role- and risk-adjusted threshold.

• Score = Σ(positive control weights) − Σ(penalties), clamped to 0–100.
• Threshold = base(role) + risk(work type) + zone(control level).
• Decision:
  • Denied if any critical item fails (ID, induction, training, required permit).
  • Approved if score ≥ threshold and no critical failures.
  • Conditional if score is close, with actions listed.
• Valid until = earliest provided expiry date (induction, training, medical, insurance).

Adjust weights and thresholds in the scoring section to match your site policy.

How to use this calculator

1. Select the person type, site zone, and work type.
2. Enter access dates and indicate after-hours status.
3. Confirm critical checks: ID verification, induction, training, permits.
4. Complete supervision, equipment inspection, PPE, and history details.
5. Click Authorize access to view decision and conditions.
6. Use the export buttons to download CSV or PDF records.

Professional guidance

1) Why site access authorization matters

Access authorization is the first safety barrier at the gate. When entry criteria are consistent, exposure drops because untrained, unverified, or improperly equipped people are stopped before work begins. A documented decision also supports fair enforcement across shifts.

2) What this calculator standardizes

The tool captures role, zone, and work type, then checks identity verification, induction, training, permits, supervision, equipment inspection, and PPE readiness. These inputs mirror common site controls and provide a repeatable workflow for both planned and unplanned visits.

3) Using weighted scoring to reduce subjectivity

The calculator assigns points to positive controls and applies penalties to gaps. The result is a 0–100 score that is easy to compare across teams. Thresholds rise for visitors, high-risk tasks, and controlled zones, reflecting elevated exposure and oversight needs.

4) Managing high-risk activities and permits

Hot work, confined space, lifting, electrical work, and work at height demand stricter authorization. If a permit is required, permit issuance becomes a critical control. For work at height, missing fall protection triggers denial to prevent uncontrolled exposure.

5) Controlling document expiries and validity windows

Expired induction, training, or insurance can invalidate otherwise strong submissions. The calculator calculates a “valid until” date using the earliest expiry provided. This encourages proactive renewals and helps supervisors schedule work within compliant windows.

6) Zone selection and supervision expectations

Restricted plant areas and high-risk zones increase the authorization bar because hazards are less forgiving. Onsite supervision scores higher than remote supervision, while no supervision reduces confidence. Conditional outcomes list actions, such as assigning an escort or confirming communications.

7) Turning results into auditable records

Compliance improves when decisions are traceable. The CSV export supports registers and dashboards, while the PDF export creates a simple authorization record for filing. Keeping the same fields across contractors and visitors makes audits faster and trend analysis cleaner.

8) Practical rollout tips for consistent gate control

Start by aligning weights and thresholds with your site rules. Train gate staff on critical failures and conditional actions. Review weekly data for repeat gaps, such as outdated training or missing inspections. Over time, the most common actions become focused improvement targets.

FAQs

1) What does “Conditional” authorization mean?

Conditional means access may be allowed with listed controls, such as added supervision, updated inspection records, or confirmed communications. It highlights gaps that are not immediate critical failures but still require action before or during entry.

2) Which items cause an automatic denial?

Failures in identity verification, missing induction, missing or expired safety training, or a required permit that is not issued will deny access. For work at height, missing confirmed fall protection is also treated as a critical failure.

3) How is the threshold determined?

The threshold starts with a base value by person type, then increases for high-risk work and higher-control zones. This mirrors typical governance: the more hazardous the task or location, the stronger the proof of readiness required.

4) Why does PPE affect the score?

PPE is a last-line control and a practical readiness signal at the gate. The checklist converts PPE completeness into a small score contribution. Missing multiple PPE items can trigger conditions because it indicates weak preparation for site hazards.

5) What does “Valid until” represent?

Valid until is the earliest expiry date among the documents you provide, such as induction, training, medical fitness, or insurance. It helps you schedule work within compliant periods and prevents relying on documents that may lapse mid-task.

6) Can I change the scoring weights?

Yes. Edit the scoring section in the file to match your policy, contract requirements, and risk controls. Keep critical failures consistent with your rules, then tune weights so the calculator supports decisions your supervisors already trust.

7) Does exporting store personal data on the server?

The exports use the most recent submission stored in the current browser session. If you need server-side retention, integrate a database and apply privacy rules. For shared terminals, reset the form after exporting to clear the session.
