Europe’s continuing heatwaves are creating challenges that extend well
beyond outdoor comfort. Industrial sites must consider how high ambient
temperatures, dry conditions, hot equipment and ongoing maintenance work
can affect workers, machinery, insulation systems and fire-prevention
procedures.
In June 2026, western Europe experienced its hottest June on record.
Copernicus also reported that the average temperature over European land
was the second-highest recorded for June. Heat continued into July in
parts of the region, while dry conditions contributed to drought and
wildfire activity.
These conditions do not mean that every industrial site will experience
a fire. They do mean that factories, shipyards, construction projects,
power facilities and maintenance contractors should review their
industrial heat and fire risks before carrying out hot
work or operating equipment under unusually hot conditions.
According to the Copernicus Climate Change Service, June 2026 was the
warmest June recorded for western Europe. The western European regional
average reached 20.74°C, approximately 3.06°C above the 1991–2020 June
average.
European land temperatures were also the second-highest recorded for June.
Much of western and central Europe experienced intense heat during the
second half of the month, following an earlier heatwave in May and before
another period of extreme heat developed in July.
Widespread dryness accompanied the high temperatures in many areas. These
conditions increased drought pressure and contributed to wildfire
activity, particularly in parts of the Iberian Peninsula and southern
France.

Europe as a whole recorded its second-highest June land temperature.
Industrial facilities already contain heat sources such as boilers,
furnaces, engines, exhaust systems, steam lines, welding operations and
heated process equipment. A heatwave adds a higher ambient temperature to
these existing conditions.
Higher ambient temperature does not automatically increase the rated
temperature of a material. It can, however, reduce the thermal margin
available to workers and equipment and make poorly ventilated work areas
more difficult to manage.
Physical work, protective clothing, direct sunlight and nearby hot
processes can increase the body’s heat load. Fatigue and dehydration
may also affect concentration and decision-making.
Welding, cutting and grinding continue to generate sparks, hot
particles and radiant heat. Dry surrounding conditions may require
more careful combustible-material control and fire monitoring.
Boilers, exhaust systems, valves, flanges and process lines may remain
hot for longer or release more heat into already warm work areas.
Ventilation and cooling systems may operate under greater demand,
particularly inside workshops, temporary enclosures and machinery
rooms.
Shipyards, construction projects, rail maintenance and field repairs
may combine solar heat, hot metal surfaces, PPE and hot-work exposure.
Damaged, wet, displaced or poorly fitted insulation can expose hot
surfaces and increase heat transfer into the surrounding work area.
Heatwave planning should focus on locations where ambient temperature and
process heat can combine. The following areas commonly require additional
review.
Sparks, molten spatter, slag and radiant heat can affect nearby floors,
walls, machinery, cables and stored materials.
Valves, flanges, steam lines and fittings may create concentrated hot
surfaces, particularly when insulation is missing or removed for
maintenance.
Marine engine rooms, generators, vehicle maintenance areas and diesel
equipment can contain exhaust pipes and components with high local
surface temperatures.
Shutdown work may introduce temporary welding, cutting, scaffolding,
cables, covers and combustible materials into an operating facility.
Ventilation systems, duct connectors and flexible joints may need
inspection when cooling demand is high or equipment is operating
continuously.
Direct sunlight, heated steel surfaces, limited shade and hot-work PPE
can increase worker thermal exposure.
Material selection should be based on the local heat source, exposure
duration, installation direction, mechanical requirements and available
test data. No single fiberglass material is suitable for every heat or
fire-risk condition.
Welding blankets can help shield nearby surfaces and equipment from
sparks, light slag, spatter and localized heat during suitable
hot-work operations.
The required fabric, thickness, coating, finished size and
installation direction should be selected according to the work.
Woven fiberglass cloth can be supplied as roll material for thermal
barriers, fabricated covers, composite structures and other
industrial applications.
Weight, thickness, weave, surface treatment and fabrication method
should be confirmed before ordering.
A silicone coating can improve surface durability, flexibility,
handling and resistance to moisture exposure, depending on the
coating system.
It is often considered for removable insulation covers, flexible
connectors, protective covers and fabricated thermal barriers.
High-silica fabric may be selected for more demanding localized heat
exposure than standard E-glass fabric, subject to the specific product
construction and test conditions.
Buyers should confirm silica content, fabric weight, weave, coating
and the temperature definition used in the technical data.
Removable covers can be fabricated for valves, flanges, pipe fittings
and equipment where insulation must be removed for inspection or
maintenance.
The outer fabric, insulation core, liner, fasteners and sewing
materials should be matched to the operating environment.
Tapes, sleeves, wraps and fabricated insulation materials may be used
around pipes, exhaust systems, equipment and localized heat sources.
Product construction should be selected according to operating
temperature, installation method, abrasion and environmental
exposure.
Ambient weather conditions are only one part of the selection process.
The temperature and behaviour of the actual industrial heat source remain
the primary considerations.
| Application | Possible Material Direction | Selection Questions |

| Flexible connectors | Coated fiberglass fabric or engineered multilayer fabric |
Movement, pressure, airflow, temperature, moisture and chemical exposure |
| Temporary heat barrier | Fiberglass cloth, coated fabric or high-silica fabric |
Radiant heat, contact risk, installation distance, fixing method and repeated use |

Equipment shape, access openings, seams, grommets, handling and inspection requirements |
EU-OSHA advises workplaces to treat excessive heat as an occupational
safety and health risk requiring assessment and an action plan. The issue
is particularly relevant to physical work, outdoor tasks, hot processes,
PPE use and poorly cooled indoor environments.
For industrial hot work, heat-stress controls and fire-prevention controls
should be coordinated rather than managed separately.
For higher-risk maintenance and hot-work environments,
welding habitat systems
may help create a controlled work zone for welding, cutting and repair
activities. The enclosure type, ventilation arrangement, pressure
control and site procedure must be evaluated for the actual project.
Where practical, move demanding work away from the hottest period of
the day and allow additional recovery time.
Consider temperature, humidity, radiant heat, workload, PPE,
acclimatisation and individual vulnerability.
Remove combustible materials where possible or provide suitable
shielding and separation around the hot-work zone.
Confirm that ventilation remains suitable for fumes and heat and does
not displace curtains, blankets or temporary barriers.
Check blankets, curtains and covers for tears, open seams,
contamination, damaged grommets or incorrect positioning.
Use trained personnel and suitable fire-response equipment according
to the site risk assessment and hot-work procedure.
Ensure workers can access drinking water, shaded or cooled recovery
areas and assistance if heat-related symptoms appear.
Inspect the opposite side of walls, decks, platforms and penetrations
where heat or sparks may travel out of direct view.
High-temperature protection systems should be inspected before they are
needed, not only after a problem occurs.
Industrial buyers should provide more than a general request for a
“high-temperature fabric.” Complete application information helps the
manufacturer evaluate a suitable construction.
Heat-resistant fabrics do not cool an entire workplace and do not remove
heat stress from workers.
A welding blanket does not make every hot-work area safe. It cannot
replace combustible-material removal, ventilation, atmospheric testing,
fire watches, extinguishing equipment, trained personnel or emergency
procedures.
The words “heat-resistant,” “fire-resistant” and “high-temperature”
should not be interpreted as unlimited protection. Material performance
depends on construction, exposure, duration, installation and the test
method used.
Facilities should follow applicable local regulations, project
specifications and their own occupational safety and hot-work management
procedures.
Ambient temperature is one factor, but the welding process, sparks,
spatter, radiant heat, installation direction and distance from the heat
source remain the main selection criteria.
The choice may include woven fiberglass, coated fiberglass, foil-faced
materials or high-silica fabric. Selection depends on heat intensity,
distance, duration, flexibility and installation requirements.
Standard fiberglass and high-silica fabric have different compositions
and thermal capabilities. Buyers should compare silica content, fabric
weight, weave, treatment and verified temperature data for the complete
product.
Silicone-coated fiberglass fabric is commonly considered as an outer
layer for removable insulation covers because of its flexibility and
coated surface. The complete cover construction must still be designed
for the actual equipment temperature and environment.
No material can guarantee that an industrial fire will not occur.
Fiberglass-based products may support heat shielding, spark containment
or insulation when correctly selected and installed as part of a wider
safety system.
Provide the application, heat source, exposure temperature, duration,
required material, dimensions, fabrication details, quantity, packaging,
destination and required documentation.
Climate conditions, warnings and workplace requirements vary by location.
Review current national weather alerts and applicable occupational safety
requirements before planning work.
