NR20 Specific Course English
The objective of this course is to enable participants to understand, interpret, and correctly apply safety requirements related to work with flammable and combustible materials. To achieve this, the content progressively addresses fundamental concepts, inherent hazards, and essential control measures aimed at reducing the likelihood of accidents, fires, and explosions. As a result, participants develop a technical and critical understanding of risk scenarios, strengthening safe decision-making in the workplace.
Furthermore, the course is designed to ensure alignment with current legal and regulatory requirements, with particular emphasis on NR-20. Consequently, participants gain the ability to recognize critical situations, interpret operational procedures, and understand the role of risk management as a core element of prevention, directly contributing to the protection of people, facilities, and the environment.
Who must attend the Specific Course for Work with Flammable and Combustible Materials?
This course is intended for workers, supervisors, and professionals who perform activities involving flammable and combustible materials, whether in storage, handling, transfer, or operational control. Therefore, anyone exposed to these substances as part of their job functions must understand the associated risks and the preventive measures required to control them.
In addition, the course is relevant for professionals involved in planning, supervision, and risk management, as it provides a solid theoretical foundation aligned with NR-20. As a result, it supports informed decision-making and strengthens compliance with legal and safety requirements.
When is this training required for workers exposed to flammable and combustible materials?
This training is required whenever a worker is assigned to activities that involve direct or indirect exposure to flammable and combustible substances. In practice, this includes onboarding, role changes, process modifications, or whenever risk scenarios are altered.
To clarify the main situations, see the table below:
| Situation | Training Requirement |
|---|---|
| New employee assigned to flammable-related activities | Mandatory before starting work |
| Change in task or process involving flammables | Mandatory prior to the new activity |
| Modification of materials or operating conditions | Mandatory update of training |
| Regulatory or procedural review | Mandatory refresher as applicable |
NR20 Specific Course English: Risk awareness is a core requirement for safe work with flammable materials
This principle reinforces that understanding hazards, exposure scenarios, and potential consequences is essential to prevent accidents. Without risk awareness, technical controls lose effectiveness and unsafe decisions become more likely.
Key aspects include:
Recognition of hazardous scenarios
Understanding ignition sources
Awareness of vapor behavior
Anticipation of accident consequences
Why is NR-20 critical for activities involving flammable and combustible materials?
NR-20 establishes the legal and technical framework for controlling risks associated with flammable and combustible substances. Therefore, it defines minimum safety requirements, responsibilities, and preventive measures that must be adopted to protect workers, facilities, and the environment.
Moreover, NR-20 integrates risk management concepts with operational safety, ensuring that hazards are identified, evaluated, and controlled systematically. Consequently, compliance with this regulation reduces accident probability and strengthens organizational safety culture.
Where do the main risks related to flammable and combustible materials usually arise?
Risks typically arise in areas where flammable substances are stored, handled, transferred, or processed. These locations often combine vapor release, ignition sources, and human interaction, increasing the likelihood of incidents.
The table below summarizes common risk locations:
| Area | Typical Risk Factors |
|---|---|
| Storage areas | Vapor accumulation, leaks, inadequate ventilation |
| Transfer and loading zones | Spills, static electricity, ignition sources |
| Maintenance areas | Hot work, inadequate isolation, procedural failures |
| Confined or enclosed spaces | Vapor concentration and explosion potential |
NR20 Specific Course English: Safe behavior directly influences accident prevention
Human behavior plays a decisive role in controlling or amplifying risk. Even with technical safeguards in place, unsafe actions, complacency, or routine-driven behavior can lead to serious incidents.
Key behavioral factors include:
Risk perception
Habitual exposure to hazards
Overconfidence due to routine
Compliance with procedures
Which benefits does theoretical training provide for professionals working with flammable materials?
Theoretical training provides professionals with a structured understanding of hazards, risk scenarios, and preventive strategies related to flammable and combustible materials. As a result, workers become capable of identifying unsafe conditions and understanding the rationale behind safety procedures.
Furthermore, this knowledge strengthens compliance with NR-20, supporting safer operational planning and more effective communication during critical situations. Ultimately, it contributes to accident prevention and the protection of lives, assets, and operations.
What is the important of the NR20 Specific Course English?
The importance of this course lies in preparing professionals to recognize, understand, and control the risks associated with flammable and combustible materials before incidents occur. By developing technical awareness and risk perception, the course reduces unsafe behaviors, minimizes operational errors, and strengthens preventive decision-making. Consequently, workers become better equipped to act safely in environments where a single failure can lead to fires, explosions, and severe consequences.
In addition, the course ensures compliance with NR-20, which establishes mandatory requirements for managing these hazards. Through theoretical alignment with this regulation, organizations improve legal compliance, enhance safety culture, and protect people, facilities, and the environment in a structured and responsible manner.

TECHNICAL CURIOSITIES – NR20 SPECIFIC COURSE ENGLISH:
The Flash Point Is Not a Detail, It Is Destiny
The flash point defines the exact moment when a liquid shifts from seemingly harmless to potentially explosive. Many accidents occur because the product was below its boiling point but above its flash point, creating invisible vapors ready for ignition.
Vapors Are More Dangerous Than the Liquid
In activities involving flammable substances, the greatest risk is rarely the liquid itself, but the vapors released. They spread, accumulate in low areas, and can travel long distances until they encounter an unexpected ignition source.
Flammable and Combustible Do Not Differ by Danger, but by Behavior
The technical difference between flammable and combustible materials lies in ignition temperature, not in damage potential. Combustible materials can be just as destructive as flammable ones when heated or atomized under improper operational conditions.
