At Oscar Sierra, we provide specialized technical solutions for respiratory protection and gas detection for fire service operations. Our work focuses on ensuring that the equipment used during interventions is fully operational, certified, and ready to perform in extreme conditions, where a failure in a protective system can have critical consequences.
We supply and service self contained breathing apparatus (SCBA) and portable gas detectors, tailored to the real-world needs of professional fire brigades and intervention teams.
Self-contained breathing apparatus (SCBA) is essential in any operation involving smoke, toxic gases, high temperatures, or oxygen deficiency. Its reliability directly determines the ability to operate safely in structural fires, confined-space rescues, or incidents involving hazardous substances.
At Oscar Sierra, we work with certified SCBA units, ensuring that cylinders, regulators, valves, and face masks meet technical specifications and provide the required air duration for extended interventions.
In addition to respiratory protection, early gas detection is essential for assessing risks during an incident response and making safe operational decisions.
Portable detectors enable the immediate identification of carbon monoxide, flammable gases, explosive atmospheres, or oxygen deficiency during an intervention. Our service ensures that this equipment is correctly calibrated and verified, with sensors and alarms in perfect working order.
As an authorized service center for Dräger and Scott, we follow official procedures and use original spare parts, ensuring certified, traceable, and regulation-compliant maintenance.
Our services include:
This approach enables fire services to plan maintenance, ensure operational readiness, and meet regulatory requirements.
We provide services to fire brigades that intervene in:
Each type of intervention requires reliable and properly maintained equipment, which is why we tailor our service to the operational reality of each force.
In fire service operations, self-contained breathing apparatus (SCBA) and gas detectors are not used continuously, but when they are deployed, it is under extreme conditions with zero margin for error. For this reason, their technical condition must ensure an immediate and reliable response from the very first second of an intervention.
Regular maintenance makes it possible to:
Inspection at an authorized technical service center, following the manufacturer’s procedures, is the only way to ensure the equipment will function correctly when the responder’s safety depends on it.
We provide service across Mallorca, Menorca, Ibiza, and Formentera, traveling to fire stations or emergency response centers for on-site inspections or equipment collection.
We offer maintenance and supply services for both municipal and consortium fire brigades as well as industrial response teams.
