Vibration in the workplace is not assessed only in general terms. Hand-arm vibration transmitted during work with hand-held tools is evaluated differently from whole-body vibration acting on the body, for example when operating a forklift truck, construction machine or other mobile equipment.

Microclimate measurement is addressed where employees experience heat, cold, draughts, dry air or significant differences between parts of the workplace. During measurement we evaluate temperature, humidity, air movement and related operating conditions so that the workplace environment, thermal or cold load and suitability of technical or organisational measures can be assessed objectively.

A fee return in the air field does not arise on its own. It is based on operating records, emission measurement, emission calculations, fuel and raw material consumption, operating hours, and data stated in the operating permit.

The ARAMIS project brings new professional bases for air quality assessment, emission balances, dispersion modelling, pollution source identification, and emission calculation. For operators, designers, investors, and municipalities, outputs on emission factors, construction dust, recycling lines, greenhouse gases, and source significance under the Air Protection Act are especially important.

A lighting measurement report is often needed for building approval, change of use, KHS inspection or verification of workplace conditions. It is not enough that new luminaires are installed in the building.

Insufficient workplace lighting is often addressed only when employees complain of eye strain, poor visibility, glare, or unsuitable working conditions. The same problem also arises at new workplaces, during reconstructions, building completion, or regional public health authority inspections.

Emission measurement can be complicated by poorly designed exhaust, missing measurement ports, short straight duct sections, turbulence, poor access or unsafe working conditions. The operator should address the measurement location already when designing technology, replacing filters, modifying the exhaust or preparing authorised emission measurement.

Emissions can in some cases be determined by calculation, for example using an emission factor, mass balance, specific production emission, or data on fuel, raw material, and solvent consumption. Calculation is not always enough, however.

From 2026, ISPOP for one-time emission measurement covers not only the measurement date but also notification of the report. The operator must ensure correct notification of the measurement date, and prepare the source, exhausts and operating regime.

Aggregation rules for air pollution sources determine whether multiple partial technologies are assessed for capacity separately or jointly. The outcome can change source classification under Annex 2 to the Air Protection Act, the obligation to hold an operating permit, expert opinion, dispersion study, emission measurement, or operating rules.

An expert opinion under the Air Protection Act is not addressed only for new sources. In some cases it must also be submitted when changing an existing listed stationary source, especially if designed output, capacity, or emissions increase, or if an operating technical condition replacing a specific emission limit is being set.

From 2026, the practical method of notifying dates and submitting data from protocols for one-off emission measurement is changing. The measurement date is now notified via ISPOP and data from the measurement protocol are reported by the authorised person using the PROTOKOL form.
