HAZARDOUS BIOLOGICAL AGENTS RISK SCREENER
Identify the exposure.Know the next step.
People. Materials. Water. Workplaces. Check biological exposure routes, controls and evidence – with a practical plan for what comes next.
ONE SCREEN. A PRACTICAL NEXT STEP.
Formal assessment recommended Escalate concerns or verify missing information.
Improvement needed Improve controls and check the change works.
Monitor Maintain controls. Not a declaration of safety.
YOUR EXPOSURE SCREEN ZA
01 Exposure profile Choose the exposure paths
02 Exposure checks Check conditions & evidence
03 Your action plan See what needs attention
IN THIS SCREEN
Your selected exposures will appear here.
Choose at least one exposure path.
Understand. Improve. Review. An exposure screen, not a diagnosis, infection probability, laboratory authorisation or statutory HBA assessment.
01 / EXPOSURE PROFILE
Where could exposure occur? Screen one work area or activity. Choose every relevant exposure path; shared programme questions are asked only once.

About this screen ↗
A screen is not a clearance. HBA regulation 6 requires a documented competent-person risk assessment and action plan, reviewed at intervals not exceeding 24 months and on earlier triggers. Regulation 7 requires a representative exposure-monitoring programme. A low-concern screen fulfils neither duty.
By exposure path Shared programme gaps can affect every path

BEHIND THE SCREEN
Better questions. Clearer decisions. Original OHSE screening rules, informed by South African HBA duties and occupational-health guidance. Not a validated exposure or infection-risk instrument.
Method & sources ↗
What this screen can tell you.
This is an original qualitative OHSE prioritisation tool: eight shared programme checks plus five questions for each selected exposure path. A single path has 13 questions; all eight have 48. It does not identify pathogens, calculate infection probabilities or safe microbial counts, assign agent groups/biosafety levels, prescribe vaccines or treatment, or certify compliance.
How the outcome is decided
Any substantial concern, immediate safety flag, health-referral flag, specialist-dependent gap or uncertain answer leads to Formal assessment recommended . Three or more concern answers within one path, or within the shared programme, also trigger formal review. This combination rule is an original precautionary OHSE design choice, not a validated or legal exposure threshold.
Other concern answers lead to Improvement needed . Monitor requires no concerns in every selected check, including assessment and programme evidence. It never means safe, compliant or exempt. Each path includes the shared checks; the result identifies when shared gaps raise the path’s outcome. Missing information does not prove contamination, infection or harm.
South African duties remain separate
The source basis is the Hazardous Biological Agents Regulations, 2022 , GN R.1887 (Government Gazette 46051, 16 March 2022), read with GN R.2693 (Government Gazette 47413, 31 October 2022). The amendment addresses vulnerable employees, training, assessment, a control provision and Annexure A. No risk-group table or ventilation pressure specification is implemented by this screen.
Regulation 6 requires a documented competent-person assessment, an action plan and reviews at intervals not exceeding 24 months, and earlier when specified changes, incidents or health findings occur. Under regulation 4, training is required before potential exposure; refresher training is annual or at intervals recommended by the committee/representative.
Monitoring is not an optional score-based extra. Regulation 7 requires a representative, competent-person exposure-monitoring programme with a suitable validated procedure, intervals determined in the assessment but not exceeding 24 months, and checks after exposure-affecting changes. This does not mean the same air sample is appropriate at every workplace; a specialist must select the appropriate method. Visual cleanliness, CO2 or one negative microbial result does not establish biological clearance.
Regulation 8 governs medical surveillance with occupational health practitioner oversight. Regulation 10(4)(g) addresses making effective vaccines available to relevant susceptible employees. Clinical suitability, testing, immunity and treatment belong to qualified health professionals, not this tool; there is no blanket vaccination or testing mandate generated here.
Regulation 9 distinguishes retention periods: risk assessment, monitoring and medical-surveillance reports for at least 40 years; specified control examinations/tests and resulting repairs for at least five years; training while employed at that workplace. Personal medical records have separate access protections and are not general committee files.
Scope & limitations
Designed for employer-managed South African OHS Act workplaces. The regulations also address self-employed persons, whose specific duties need separate review. Incidental exposure can matter as much as deliberate work. A documented Group 1-only exposure has limited exclusions under regulation 2(2); it is not a blanket exemption and this screen never assumes that classification.
Clinical infection control, public-health responses, high-containment work, agent/shipping classification, food-safety assurance and specialist permits require their own competent decisions. This tool provides no organism handling, culture, disinfection recipe, containment design or waste-treatment procedure. Confined-space, gas, chemical, physical-agent and machinery hazards need separate assessments and controls.
Urgent events & privacy
Do not wait to finish if a potentially significant exposure or uncontrolled release has occurred. Use the workplace emergency and reporting arrangements and seek appropriate urgent clinical help. Possible rabies or bloodborne exposure needs prompt professional assessment, not a quiz result or a wait for symptoms.
Do not enter names, diagnoses or other medical details. Answers are held only in page memory and are lost on reload. Downloaded, copied and printed reports contain the answers and must be handled appropriately. The email enquiry excludes your area label, headcount, symptoms and individual answers; it opens a draft and does not send it.
