| Patients, physicians and employers should be informed that persistence of exposure to the causal agent is likely to result in a deterioration of asthma symptoms and airway obstruction | Strong | Moderate |
| Patients and their attending physicians should be aware that complete avoidance of exposure is associated with the highest probability of improvement, but may not lead to a complete recovery from asthma | Strong | Moderate |
| Reduction of exposure to the causal agent can be considered an alternative to complete avoidance in order to minimise adverse socio-economic consequences; however, there is insufficient available evidence to recommend this option as a first-choice therapeutic strategy. This approach requires careful medical monitoring in order to ensure an early identification of asthma worsening | Weak | Low |
| The use of respiratory protective equipment should not be regarded as a safe approach, especially in the long-term and in patients with severe asthma | Strong | Low |
| Anti-asthma medications should not be regarded as a reasonable alternative to environmental interventions | Strong | Very low |
| The pharmacological treatment of work-related asthma should be adapted to the level of asthma control, in accordance with the general recommendations for asthma | Strong | Moderate |
