Benzene
Sources, monitoring, health surveillance and Annex 13-A controls must be checked.
Brazilian Employment Law · Vale do Aço/MG
Coke ovens, blast furnaces, steelmaking, rolling, maintenance and laboratories do not involve the same exposure. Chemicals, heat, noise, medical records and social security documents must be assessed by department and period.
General legal information. Any entitlement depends on the facts, records, collective rules and, where applicable, expert evidence.

Benzene and chemicals
Prevention, monitoring and evidence of exposure
OAB/MG No. 230.667
Professional registration in Minas Gerais, Brazil
Employment and social security law
Supplements, health, PPP and qualifying hazardous service, with distinct criteria
Carcinogenic agent
NR-15 recognises benzene's carcinogenic nature and sets out specific prevention and health surveillance measures.
Annex 13-A of NR-15 classifies benzene as a proven carcinogen and states that no exposure is safe. For steelmaking, the standard sets a technological reference value to guide control measures, rather than a limit that removes the risk.
The department, emission source, tasks, duration, ventilation, environmental monitoring, respiratory protection and health surveillance must be examined for each period. A company name or job title does not replace this reconstruction.
Any unhealthy working conditions supplement, causal link to illness and recognition of hazardous work for social security purposes have different requirements. Reports and exposure history may inform each other but do not automatically produce the same outcome.
Situations we assess
Assessment is individual to the area, role, period and agent, including directly employed and outsourced workers.
Areas of assessment
The list helps identify relevant issues, but cannot establish that a particular payment is due without examining the case.
Sources, monitoring, health surveillance and Annex 13-A controls must be checked.
The product, composition, exposure route and NR-15 classification vary by process.
Measurements, duration, protection and limits applicable to the period require technical assessment.
Diagnosis, exposure history, serial examinations and causation must be assessed by qualified professionals.
Role, department, agents, measurement method and responsible professionals must be consistent with environmental documents.
Social security criteria vary by period and differ from the employment law supplement.
Rotas, shift handovers, breaks and overtime may also form part of the assessment.
Documents from the provider and plant may be needed to reconstruct the environment and responsibilities.
Initial advice identifies the facts, periods and records that need checking.
Employment time limits
As a general rule, the Brazilian Constitution allows two years after the contract ends to bring proceedings, and limits recovery to entitlements from the five years before the claim is filed.
2 years
General period from the end of employment for bringing an employment claim.
5 years
General reach of entitlements preceding the claim, subject to the particular circumstances.
In occupational illness cases, the dates of diagnosis, awareness of incapacity, absence and benefits may affect time limits. Preserve medical and employment documents.
Organising documents
You do not need every document at first contact. The aim is to identify what exists and what will need to be requested.
Versions from the relevant period, responsible professionals, agents, measurements and stated methodology.
Risk inventory, environmental assessments and control records, where available.
ASO occupational health certificates, serial examinations, medical certificates, CAT accident notifications, medical records and related benefits.
Employment record book, contract, payslips, instructions, training and assignment history.
Records, certificates, replacement, training and actual conditions of use.
Agreements addressing supplements, health, shifts and conditions specific to the sector.
Transparency
The activity, sector or an isolated impression cannot replace assessment of facts and evidence.

Frequently asked questions
General answers for guidance. Conclusions depend on the records and circumstances of each contract.
No. The department, agent, intensity or concentration, duration, protection and classification under NR-15 must be established. The industry alone does not determine entitlement to the Brazilian insalubridade supplement.
Annex 13-A of NR-15 treats benzene as a proven carcinogen and states that there is no safe exposure. The technological reference value guides prevention and must not be interpreted as a limit that eliminates the risk.
It would be irresponsible to make that general claim. The supplement and its rate depend on the legal classification, activity, exposure and technical evidence applicable to the case, as well as any collective agreements.
A correction may be requested where the data do not reflect the environment, role or agents. Expert reports, the PGR risk management programme, the LTCAT workplace conditions report and records from the period help support the correction.
No. Exposure evidence may be relevant to both, but employment and social security requirements are distinct and vary according to the period.
No. Assessment requires a diagnosis, occupational history, medical monitoring and investigation of other causes. Clinical care must be provided by healthcare professionals.
